Thank you, I noticed that the few other videos didnt give enough detail so wanted to make sure I included everything I could on properly placing the components. Hopefully this helps!
@@ExtremeDIYGuy I did the little test as well, put the pump on my outboard today, ran the engine for just a second,(even tho my impeller isn't working correctly) .. I'm positive the pump is working as it should. Should have that Evinrude running like a top pretty soon...... I do have a question tho. So I have an old metal gas tank, it was rusted out when I got it, I threw a bunch of gravel in it and shook it around for 20 min or so, then I filled it with vinegar and let it soak overnight. That seemed to clean the tank really well. I rinsed it out with gas then I filled it, then I rebuilt that fuel pump. But I also put on a fuel filter just after the bulb, just to insure that the gas is clean before it flows through my freshly built pump. Will that filter make that pump work harder then it should? Hope that isn't a dumb question ... I'm probably over thinking it.
@@Rockers1121 I wouldn't think so. The fuel filter shouldn't impede the flow of gas by very much. I think it's a good precaution to take to help protect the pump and engine.
@@ExtremeDIYGuy i put my fuel pump back together 5 different times and when i blow thru it its just free flowing air like blowing thru a straw any advice would help???
We were expecting a fuel filter and had no idea what we were doing when we started pulling this thing apart. What a crazy contraption. Followed your video then searched for that stupid plastic piece on the small spring and found it in the cockpit by some miracle. Using your video got the engine working but it kept dying after a minute or two. Rebuilt the filter again paying real close attention to that friggin spring to make sure it didn't fall over and now everything works. Really appreciate the detailed video. Now we're back in the water.
Finally got the fuel pump serviced properly after watching this video. Thank you so much! Now to figure out why bottom cylinder is not firing on a 75 Johnson 6hp… Cheers again for the instructions!
Thanks! I disassembled mine outside and the tiny spring sprung and hit the grass. I found it immediately, but because of the 2 spring slots I thought I lost one. Now I see I have all the parts. Your video is so detailed I know I can rebuild and reassemble it the correct way.
Dab a very small amount of petroleum jelly, which is gasoline soluble, on each end of the small spring and you will save yourself so many headaches. Cannot stress enough to take photos of the inlet and outlet port locations. I can see how much this would cause grief. I actually recorded on my camera disassembly and had to go back and watch it to align it up correctly. Good video BTW.
That's a great tip! Yeah, the inlet and outlet ports are probably the biggest cause of failed re-assemblies. I tried my best to show and explain how they should be positioned. Hopefully it helps!
I know this video is old but buddy you are a my go to from here on. That tiny spring took me by surprise. This video was perfect right to blowing into the line to see if it was done right. Thank you
Lol I just did the same exact fuel pump watching this video as I did it, It goes to a 1972 Evinrude fisherman, I just put new points and condenser's in it too, now I'm waiting for a new impeller. ... Gonna see how the engine runs when I'm done with that. If it still runs a little funny then I'll rebuild the carburetor. This video helped a lot ! Saved me 120 bucks for a new fuel pump. I think .. I haven't tested the fuel pump yet, I just now got done rebuilding it. We shall see in a few days after I rebuild my water pump.
Mate you are a God send. We purchased a kit, FMD it may as well have been written in hieroglyphics. I pulled the thing down for the 3rd time and followed you step by step. I am again the grandsons hero and go to. Started first kick and purrs again. We are off for a weekend fishing thanx to you, otherwise we would have been towing it as a row boat. Thanx from Australia.
Great video; Thanks! Just as a heads up....another issue with these pumps is sticking or damaged check valves. The check valves are in the thick plastic part that is not included in either the OMC or Sierra kits. I have done a enough of these rebuilds to be confident that I had everything assembled properly and it still would not work. I looked closely at the two check valves and saw that one of them was stuck. I soaked it in carb cleaner for a couple of hours and all was good. Something to consider if you rebuild and still have problems.
Great video - Finally understand how to rebuild . BTW ...spent hours looking for that little spring that fell in pea gravel ! I had a tarp but the spring 'jumped" past the tarp.
The cardboard and nails idea is genius. I've got a problem where the hose is siphoning back to the tank if the motor is shut off for more than about 3 minutes. I think the ball on top of the spring is my problem. Thanks for breaking this down. In the next life you can scratch "being a teacher" off your list, you've mastered that in this life.
Excellent video. You created a well-documented, easy to follow video version of the OEM manual for this project, especially the part dealing with the placement of the small spring.
Had about given up on rebuilding those pumps as I always managed to do something wrong while trying to put it back together. Thanks to you, success is IN and frustration is OUT ! I say Jose for president !
Thanks so much for explaining the spring positioning, the instructions weren't that clear to me. Best video in you tube about how to service this fuel pump.
Tip: After blowing in both ends, blow into intake again, but plug output with your finger. If air still flows, you have an improper gasket seal and fuel will leak. Fix before installing.
This is very helpful. I have an old Evinrude 6hp that gives me trouble with cold starting. I have gotten to the point that I suspect the fuel pump. Also, never use brake cleaner on anything plastic. It dissolves plastic. I found this out the hard way. Good thing you corrected your post to say carb cleaner.
You are a life saver. On the metal plate mine did not have the "U" on it. I put the crown side up and it worked. The first time I did it I must have put the crown side down and the screw for the last piece (filter) would not thread (wouldn't reach). Re-did the whole thing watching your vid and viola. Excellent instructional vid. Thanks.
This was very helpful. Thanks. I made the mistake of opening my old one before I knew anything about the springs and diaphragms. Everything fell apart in my hands. Luckily I found your video. Thanks again.
Great video and thanks for the explanation on the orientation of the output and the spring location. I took mine apart and lost track of the order of the gaskets and diaphragms. The instructions were OK but where the spring goes was not clear. Thanks again!
Again, the end, where the up on the plate lines up with the outlet, and not the big up arrow ... and blowing in and getting the duck noise ... saved my bacon ... thanks!!!
great video. I just installed a new pump on a1975 evinrude 9.9 and it does not work well. I have a fuel filter between the pump and the carb and I can see it runs out of gas when the fuel tank is below the motor but will run good when I elevate the tank above the motor. My compression is 100 psi on both cylinders so that's not the problem. I think I will take it apart and see if it is put together right. thanks
the new pump was put together right but it failed the blow test. [ no noise] also the outlet only had a pinhole so i drilled it out but it still did not make a noise. I had the old one that I pulled off and it was still good [made noise]. So the old one is working and the new one is not. thanks
Great video, mine is from 1990 6 hp Johnson , exact same as your pump. My problem was who ever rebuilt it before put the small spring in the wrong spot? So your video explained in detail each step. Life saver, thank you! Excellent!
Great video! I'm going change the fuel pump and was wondering if the 18-7350 Sierra will fit in my Evinrude 4 hp Deluxe year 1986 outboard. If not what fuel pump should I use in it? Thanks!
Great video boss man! I tried once and lost the microscopic dome support piece in my garage so I brought the fuel pump up to the living room and used your cardboard trick it worked great! Finally found the dome support piece and put it all back together
I rebuilt mine with a OEM kit 2 yrs ago no problem except I noted the gasket for intake cover was a soft cork material witch I thought ok but it did work well and sealed. but the end of this season I took the boat out and the gasket like shrank or what ever and leaked fuel all over. I tried fiddling with it to get it to seal but only ended up in cracking the intake cover so I ordered the parts OEM but they sent me a hard cork gasket for the cover this time and now I`m real worried about being able to tighten the intake with out cracking it again. Got eeby geebys for bit so now I`m letting it set til spring to do the repair maybe I`ll be a bit more confident about the install.
I just rebuilt the pump on my 1977 9.9hp Unfortunately I do not get that horn sound, even tho the pumps are identical and I assembled it exactly as you did. Im pretty sure Im missing out something, so Ill get back to work. Thank you for the amazing video !
Good deal! I did this video because everything else out there seemed to lack guidance on how to re-assemble. Hope your rebuild makes your engine run awesome!
@@ExtremeDIYGuy Thanks for that...I cleaned out the petrol pump this morning and just finished cleaning out the carbs which where spotless... I still have the same problem. Where is the idle mix.. is that the long screw. Lean And Rich. can you also tell me where is the idle speed ? thanks Tony
Hey man so I put everything back exactly right but it doesn’t make like a little horn sound I do get air through it and I can’t get air through the outtake unless I suck on it so is that like an every time thing or should I just get air through it? Because I hope I don’t have something wrong since it won’t make the horn sound. Ha ha ha
After watching this video, I think it's easier to start from the cap, nit the base and just use the assembly screws instead of the nails. This allows the spring caps to be placed in the correct position and they aren't falling over as easily. Otherwise, it's a great video! Thank you.
I’m pretty sure i did everything correctly however, when i do the ”test” and blow thru the outlet theres air comming out the inlet, i have assembled it about 5 times now and still the same problem. Any tips?
So is it critical that you get the horn sound when blowing though the inlet? I can blow air through the inlet and not the outlet, just don't get the horn sound.
Hey man in the middle of putting mine back together just got the same kit. My question is could those two little yellow valve circles in the middle be blown out essentially? Im not saying I have that problem it’s just a thought I’m having. They look to be like the squirt nozzles on the end of a water bottle or something if you catch my drift.
I noticed that the few other videos didnt give enough detail.... That what i thought after watching the other videos. I have a new Pump, and a used one, both are leaking if i prime the Engine, think they are both not working right. During priming only the overflow of the Carb should leak. Or is OMC different there? Dont think so.
Your pump should definitely not be leaking when priming the engine. Sounds like there's a problem with the pumps. Also, if the float is working right on the carb, fuel should be shut off when the bowl is full. I would be careful not to over prime the engine and stop when the bulb starts getting firm. Not sure if that helps but worth considering.
nice video - i have my dad's 1975 15 hp that hasn't been started in decades, and by following you're instructions, realize the fuel pump is missing a gasket. Arrrgh . Have any videos on how to check if the pull start motor is even sparking?
I'm glad this video helped! I don't have a video on that yet but plan on doing one early this summer. You could use an inexpensive spark tester (with the small neon bulb) that sits inline between the wire and the plug. It wont measure the strength of the spark but should tell you if you are getting some juice to the cylinder,
@@ExtremeDIYGuy Thanks for the hint - picked up a spark tester and no luck with a spark. Any chance you'd be willing to give me a bit of guidance with next steps. Not sure how to send a direct message via you tube. Thanks, Dan
@@danhelsel6253 Not getting a spark at all or a very weak one gets a bit more complicated to troubleshoot. You'll need to check the coil first and work your way back from there. itstillruns.com/test-marine-outboard-motor-coil-8572972.html If you have an electronic control module that would be then next suspect. If not, pull the flywheel and check pints and condenser. There's a lot more to it than I can put in a response but here is a good place to start.
Hi, I have an 1997 Evinrude 8 Hp 2 stroke. I'm having trouble starting to cold. I also changed the piston rings (the cillinder compression was 80 psi) , the spark plugs, I cleaned its carburetor and it still doesn't start. It starts very very hard only with the shock pulled and the acceleration at maximum. After starting for the first time this way, the following starts are very easy. Can you advise me what to do? Thank you.
I would check the choke to make sure that it is working correctly. If I'm not mistaken, you should have an electric choke system that squirts fuel into the engine to help with a cold start. If that is correct you need to check the red switch, there is a normal position for it. If it is in the normal position, you can move it to the manual start and then switch it back when it starts. If you have to do this, the primer assembly has probably failed. The normal position has the red switch facing the body, the manual position is facing the opposite. I have a video that describes this for a larger engine but the concept is the same. ua-cam.com/video/g8FCLGfFnJ4/v-deo.html Let me know how that goes.
Thank you for answer :) Hi, the shock is mechanical, not electric. Is simple. Today I opened the carburetor (again) - I reduced the fuel level in the carburetor a little - the float had a small stroke before, I mounted it again and it does the same - it doesn't start. I also took off the spark plugs - and they were wet after the test. I checked the ignition system and it sparked.
Thanks for your help, love the part when you scraped it all in a box and started over.👍.... thanks again hope you do one for points replacement I have a 1969 6 hp
Can the outlets be reversed? I bought Carbman 18-7350 Fuel Pump Replacement for Johnson Evinrude Seahorse Outboard Motor 6hp and the fuel in and out nipples are the opposite orientation to the pump I took out..
IT can be oriented in whatever direction you need it to be. Look at 9:00 on the video and it explains how to make sure the air dome spring is correctly located for the orientation you need the outlet to be in. Hope this helps.
@@ExtremeDIYGuy I just followed this 12 times, no whistle noise and its easier to blow through the outlet than the intake. then I tried it in every orientation. No joy. I'm going to step away and try again tomorrow. I didn't test it before I took it apart either so don't know if its a dud..
@@dylanlysaght3052 Better luck with it tommorow. Try this link, it has copies of the original manual and may help. www.leeroysramblings.com/Rebuilding_fuelpump.htm
Did as your vid for my 1991 evinrude. 9.9. but still had issues. changed kit in carb too, new plugs, new fuelines...first rebuild of fuel pump, foward gear coughing...second try. bladder was squizy...third time....(what did i miss...)...did exactly as your vid this time, inch by inch...now reverse gear died on me isntantly...and engine is coughing slightly i forward gear...
IT sounds like there may be some other issues going on with that engine. Coughing engines can be caused by timing as well. Not sure if you checked that.
Hi, just put new pump together was leaking thanks, am i seeing things or do u have the outlet up side down, mine is at the bottom, or doesn,t matter? Very hard to blow air through but does go and make sound does that sound ok or should it go through very easy. UPDATE: took it apart and put back together 6 or 7 times and I can't get any air flow through either one of the tubes can somebody tell me what's wrong
Hi, i just follow the step 2 time. Everything look good because no air pass when i blow in it but when its install on the motor there a fuel leak... any idea ?
Do they all make this sound when you blow in them . I bought a new one and it doesn’t make the horn sound at all. I also put it on my engine and there is no fuel coming through the outlet
As I understand it, that gasket wasn't used on the older pumps and is optional when rebuilding. Probably should have put it in but opted not too since it did not have it originally.
You did a great job. I purchased a new pump but a knockoff . Terrible quality. Took it apart the diaphragm was kinked , one vent hole was not drilled. Terrible quality. I have the rebuild kit for my oem pump and I will be using your video to install. Thanks again and love your videos keep up the great work
Small spring positioning: To be clear. What you mean is: IF the outlet nipple (outgoing hose hookup) is in the same quadrant/corner/exits from 1 of the two possible spring positions' corners, then the spring goes right there. If not in same corner then the spring goes in the next adjacent clockwise/counterclockwise spring position that you come to. Clockwise/counterclockwise is based on if you were pointing AT the fuel hose outlet nipple. And I think there's one more way to explain this with respect to that little vent as well. I kninda did this for me and for you and for everyone...cause I want to understand. I KNOW you want to help and sometimes, 3 different ways of thinking about gives the best answer. Calling for Peace with Jose. Thx again, my friend.
Thanks Kevin. I posted a link in your other comment that has a very clear explanation on where everything goes. Hopefully that will clear it up for anyone that needs it. Thanks again.
It all depends on witch direction the outlet faces for the base of the build not all motors had the outlet facing the same way even though it was the same pump in each that is the only thing that really confuses most folks. But you have to make sure the metal base has the arrow on the tab facing up when mounted then you can go from there like I did.
driving me crazy man. I am 100% on everything, but I cannot get the horn sound and output lets air through that way. What gives. Anyways, great video, very much appreciate you taking the time to put it together.
Anyone put their fuel pump back together and when u blow thru it its just free flowing air no noise ive re oriented the spring n intake every direction possible still nothing what am i doing wrong anyone else have this issue??? Help plz
Dude...you STILL didn't explain thetiny spring placement properly/well enough. I'm way engine savvy but you wander off and switch-up your explanation reasoning right at. Up til then it makes sense. You tell , why, EXACTLY...in each position we put it "here" or there. You 'splained it 1-1/2 times and then assumed we knew the logic. Don't misunderstand. I'm only pissed b/c I'm overdue to fix this stupid thing and SOOOO close! A 1000 kudos for a job well done, honest. Thank you. It's just that the tiny spring part got presumptive pretty fast. In one position it's near the outlet. In one position you associate it's position with the vent port...just a little disjointed IMHO. Not trying to be a dick. Best I've found so far...and thx again.
I made the video because all the other ones I found weren't complete so wanted to do one that explained it a bit better. Here's a link to a page that might help you. bit.ly/3hvQL7n

Incredible. How could they divice a complicated pump like this back in the days? Thanks for an informative vid!
Good question!
Use a bit of petroleum gelly (vaso) to help stick the springs in place
That's a great idea, thanks for the heads up.
My Seahorse Stops when I drop revs to Slow position... Its just dies.. Any idea !! could it be the idle jet in the carb ! Thanks
It could be the idle mix adjustment but you should also check the idle speed, might be too low
@@ExtremeDIYGuy Thanks for that...I cleaned out the petrol pump this morning and just finished cleaning out the carbs which where spotless... I still have the same problem. Where is the idle mix.. is that the long screw. Lean And Rich. can you also tell me where is the idle speed ? thanks Tony
is the idle adjustment screw lower down on the tiller arm !! thanks
On most outboard the idle mix is right on the carb, the idle speed is on or connected to the linkage going to the carb.
@@ExtremeDIYGuy Thanks. Im gona have another go at it today thanks
Hey man so I put everything back exactly right but it doesn’t make like a little horn sound I do get air through it and I can’t get air through the outtake unless I suck on it so is that like an every time thing or should I just get air through it? Because I hope I don’t have something wrong since it won’t make the horn sound. Ha ha ha
You may or may not get the horn sound when it's built correctly. So it may be fine but no horn sound!
@@ExtremeDIYGuy Sounds good to me thanks for the reply.
After watching this video, I think it's easier to start from the cap, nit the base and just use the assembly screws instead of the nails. This allows the spring caps to be placed in the correct position and they aren't falling over as easily. Otherwise, it's a great video! Thank you.
Your welcome, sounds like a good way to do it, worth giving it a shot.
Fantastic... You should have seen the smile on my face when I got the Horn Sound.. Thanks you saved me a huge amount of STRESS... thanks...........
Glad I could help!
Cool trick with the nails and cardboard. Smart!
Thanks!
I’m pretty sure i did everything correctly however, when i do the ”test” and blow thru the outlet theres air comming out the inlet, i have assembled it about 5 times now and still the same problem. Any tips?
Thanks man just helped me get my boat running again I had the pump put on wrong
Your welcome Austin!
Top class very helpful had mine apart and together 4 times had valve spring in wrong place great video
Glad you got it figured out !
So is it critical that you get the horn sound when blowing though the inlet? I can blow air through the inlet and not the outlet, just don't get the horn sound.
I don't think it's critical as long as it flows in one direction and not the other.
Great video's.. Could you maybe do a Yamaha 2 stroke oil line bleed as I could not find any vlogs in the past.. Cheers mate
I don't have that Yami anymore but when I will check that out on my next one. Willing to do it (as long as it's in the service manual).
Does it have to sound like a trumpet if assembled properly? I don’t get that horn sound but do hear a little popping sound like a diaphragm is moving.
No it doesn't. Should blow freely in one direction and not flow at all in the other.
I bought a new pump and it does not make the horn sound. Does this mean it it bad. Do they all make the sound?
No, the horn sound is optional. Iff it's there it's a confirmation that everything should work. If its not could still be good.
thank you
This was a perfect breakdown of a simple yet confusing task, my boat runs again! Thanks!
Your welcome Will!
Hey man in the middle of putting mine back together just got the same kit. My question is could those two little yellow valve circles in the middle be blown out essentially? Im not saying I have that problem it’s just a thought I’m having. They look to be like the squirt nozzles on the end of a water bottle or something if you catch my drift.
Thats possible, not sure that a rebuild would help in that case.
I noticed that the few other videos didnt give enough detail....
That what i thought after watching the other videos.
I have a new Pump, and a used one, both are leaking if i prime the Engine, think they are both not working right. During priming only the overflow of the Carb should leak. Or is OMC different there? Dont think so.
Your pump should definitely not be leaking when priming the engine. Sounds like there's a problem with the pumps. Also, if the float is working right on the carb, fuel should be shut off when the bowl is full. I would be careful not to over prime the engine and stop when the bulb starts getting firm. Not sure if that helps but worth considering.
nice video - i have my dad's 1975 15 hp that hasn't been started in decades, and by following you're instructions, realize the fuel pump is missing a gasket. Arrrgh . Have any videos on how to check if the pull start motor is even sparking?
I'm glad this video helped! I don't have a video on that yet but plan on doing one early this summer. You could use an inexpensive spark tester (with the small neon bulb) that sits inline between the wire and the plug. It wont measure the strength of the spark but should tell you if you are getting some juice to the cylinder,
@@ExtremeDIYGuy Thanks for the hint - picked up a spark tester and no luck with a spark. Any chance you'd be willing to give me a bit of guidance with next steps. Not sure how to send a direct message via you tube. Thanks, Dan
@@danhelsel6253 Not getting a spark at all or a very weak one gets a bit more complicated to troubleshoot. You'll need to check the coil first and work your way back from there. itstillruns.com/test-marine-outboard-motor-coil-8572972.html If you have an electronic control module that would be then next suspect. If not, pull the flywheel and check pints and condenser. There's a lot more to it than I can put in a response but here is a good place to start.
Hello…I’ve put it together 3 times…no horn sound…the output is right tho…any thoughts?
Any thoughts from anyone?
It should be fine, as long as the output is right, the horn sound is just a confirmation but wont necessarily be there.
Thanks so much
Great video, this clears up some prior misconceptions on my part!
Thanks
Sir...will this kit rebuild my 2000 8 HP Johnson... 18-7823 thx
Where does the small aluminum disk go
In the center of the diaphragm sheet with the big spring on top ,On the OEM kit they are glue together to make things easier,
Hi, I have an 1997 Evinrude 8 Hp 2 stroke. I'm having trouble starting to cold. I also changed the piston rings (the cillinder compression was 80 psi) , the spark plugs, I cleaned its carburetor and it still doesn't start. It starts very very hard only with the shock pulled and the acceleration at maximum. After starting for the first time this way, the following starts are very easy. Can you advise me what to do? Thank you.
I would check the choke to make sure that it is working correctly. If I'm not mistaken, you should have an electric choke system that squirts fuel into the engine to help with a cold start. If that is correct you need to check the red switch, there is a normal position for it. If it is in the normal position, you can move it to the manual start and then switch it back when it starts. If you have to do this, the primer assembly has probably failed. The normal position has the red switch facing the body, the manual position is facing the opposite. I have a video that describes this for a larger engine but the concept is the same. ua-cam.com/video/g8FCLGfFnJ4/v-deo.html Let me know how that goes.
Thank you for answer :) Hi, the shock is mechanical, not electric. Is simple. Today I opened the carburetor (again) - I reduced the fuel level in the carburetor a little - the float had a small stroke before, I mounted it again and it does the same - it doesn't start. I also took off the spark plugs - and they were wet after the test. I checked the ignition system and it sparked.
Thanks for your help, love the part when you scraped it all in a box and started over.👍.... thanks again hope you do one for points replacement I have a 1969 6 hp
Thanks for watching! Yeah, sometimes you have to just back up and start over, Better to do it right the first time around!
What did i do wrong if my pump is pumping air?
It sounds like one of the gaskets failed or was put in wrong. I would disassemble and start over.
Can the outlets be reversed? I bought Carbman 18-7350 Fuel Pump Replacement for Johnson Evinrude Seahorse Outboard Motor 6hp and the fuel in and out nipples are the opposite orientation to the pump I took out..
IT can be oriented in whatever direction you need it to be. Look at 9:00 on the video and it explains how to make sure the air dome spring is correctly located for the orientation you need the outlet to be in. Hope this helps.
@@ExtremeDIYGuy i was going to use longer fuel lines instead, but i might try this, thanks.
@@dylanlysaght3052 Your welcome, let us know how it goes!
@@ExtremeDIYGuy I just followed this 12 times, no whistle noise and its easier to blow through the outlet than the intake. then I tried it in every orientation. No joy. I'm going to step away and try again tomorrow. I didn't test it before I took it apart either so don't know if its a dud..
@@dylanlysaght3052 Better luck with it tommorow. Try this link, it has copies of the original manual and may help. www.leeroysramblings.com/Rebuilding_fuelpump.htm
What size fuel line goes to the pump I need to replace mine
I no longer have this engine so don't know of the top of my head. Sorry
Did as your vid for my 1991 evinrude. 9.9. but still had issues. changed kit in carb too, new plugs, new fuelines...first rebuild of fuel pump, foward gear coughing...second try. bladder was squizy...third time....(what did i miss...)...did exactly as your vid this time, inch by inch...now reverse gear died on me isntantly...and engine is coughing slightly i forward gear...
IT sounds like there may be some other issues going on with that engine. Coughing engines can be caused by timing as well. Not sure if you checked that.
Hi, just put new pump together was leaking thanks, am i seeing things or do u have the outlet up side down, mine is at the bottom, or doesn,t matter? Very hard to blow air through but does go and make sound does that sound ok or should it go through very easy. UPDATE: took it apart and put back together 6 or 7 times and I can't get any air flow through either one of the tubes can somebody tell me what's wrong
I posted a link to copies of the manual on Leroys ramblings page. Might be helpful
Thanks my friend i actually got the pump all together, did engine rebuild and it just started , your video did help to some extent, Thax.
Hi, i just follow the step 2 time. Everything look good because no air pass when i blow in it but when its install on the motor there a fuel leak... any idea ?
All I can think of is that one of the gaskets is compromised but not visible when assembling it. Perhaps the rebuild kit was defective?
Everything look in good condition after re done a few time is still leaking by the vent where my air dome is. Still dont understand why its leaking
@@legaultpatrick4513Sorry to hear that, I can only imagine that one og the gaskets is somehow compromised.
Do they all make this sound when you blow in them . I bought a new one and it doesn’t make the horn sound at all. I also put it on my engine and there is no fuel coming through the outlet
I don't think so, it should blow freely in one direction and not at all in the other. Mine just happened to be a little bit musical lol
Couldn't you just rebuild it,and spin the plate under the diaphragm to line up with the application needed?
You just saved my fishing trip with this Video.... My pump had 3 extra parts in it 🤣
Glad I could help!
They all do I think
Where the big spring go?
Right above the bottom membrane 6:59 in the video shows where.
I was wondering why you didn’t use the base gasket?
As I understand it, that gasket wasn't used on the older pumps and is optional when rebuilding. Probably should have put it in but opted not too since it did not have it originally.
I have a 1977 Johnson 4 ho seahorse . Any idea of this kit will work for my motor
I think that it will but you can check on marineengine.com and cross reference the part # there.
Just rebuilt the new one just like you did step for step and I got nothing lol.
@@scottyfixer452 Sorry it didn't work out for you.
You did a great job. I purchased a new pump but a knockoff . Terrible quality. Took it apart the diaphragm was kinked , one vent hole was not drilled. Terrible quality. I have the rebuild kit for my oem pump and I will be using your video to install. Thanks again and love your videos keep up the great work
Brilliant!! Thanks, worked a treat!
You're welcome!
Sir petrol leak vacuum pump video show me ?
I'd like to help but I'm not really sure what you are asking.
Very interesting video. Very easy to understand. Thank you
You are welcome!
Small spring positioning: To be clear. What you mean is: IF the outlet nipple (outgoing hose hookup) is in the same quadrant/corner/exits from 1 of the two possible spring positions' corners, then the spring goes right there. If not in same corner then the spring goes in the next adjacent clockwise/counterclockwise spring position that you come to. Clockwise/counterclockwise is based on if you were pointing AT the fuel hose outlet nipple. And I think there's one more way to explain this with respect to that little vent as well. I kninda did this for me and for you and for everyone...cause I want to understand. I KNOW you want to help and sometimes, 3 different ways of thinking about gives the best answer. Calling for Peace with Jose. Thx again, my friend.
Thanks Kevin. I posted a link in your other comment that has a very clear explanation on where everything goes. Hopefully that will clear it up for anyone that needs it. Thanks again.
It all depends on witch direction the outlet faces for the base of the build not all motors had the outlet facing the same way even though it was the same pump in each that is the only thing that really confuses most folks. But you have to make sure the metal base has the arrow on the tab facing up when mounted then you can go from there like I did.
can i replace my evinrude 15 hp 4 stroke pulse type fuel pump with a 2 stroke fuel pump
I wouldn't, I would at the very least use an aftermarket pump that cross references to the original part number.
@@ExtremeDIYGuy thank you very much sir
@@eamoncinco7623 Your welcome!
driving me crazy man. I am 100% on everything, but I cannot get the horn sound and output lets air through that way. What gives. Anyways, great video, very much appreciate you taking the time to put it together.
Not sure, Hate to say it but you may have to go through it one more time. also make sure there are no tears on the soft rubber pieces.
Excellent video!!! Thanks for posting
Glad you enjoyed it!
Very well explained! Thank you!
Your welcome!
Thanks. Really well done.
Thank you too!
Thank you very much your instructions where a tremendous help.
No problem!
Anyone put their fuel pump back together and when u blow thru it its just free flowing air no noise ive re oriented the spring n intake every direction possible still nothing what am i doing wrong anyone else have this issue??? Help plz
I'm nit sure I can help. Is it possible there's a tear in one of the diaphragms?
@@ExtremeDIYGuy i figured it out the top plate was turned the wrong way my fault
@@jamesmull2832 Good deal, Glad you got it figured out!

Thank you now I know how to rebuild my fuel pump great video much info thanks again
Your very welcome Sam!
Thanks heaps brother helped me out so much with this video
Glad to hear it!
Dude...you STILL didn't explain thetiny spring placement properly/well enough. I'm way engine savvy but you wander off and switch-up your explanation reasoning right at. Up til then it makes sense. You tell , why, EXACTLY...in each position we put it "here" or there. You 'splained it 1-1/2 times and then assumed we knew the logic. Don't misunderstand. I'm only pissed b/c I'm overdue to fix this stupid thing and SOOOO close! A 1000 kudos for a job well done, honest. Thank you. It's just that the tiny spring part got presumptive pretty fast. In one position it's near the outlet. In one position you associate it's position with the vent port...just a little disjointed IMHO. Not trying to be a dick. Best I've found so far...and thx again.
I made the video because all the other ones I found weren't complete so wanted to do one that explained it a bit better. Here's a link to a page that might help you. bit.ly/3hvQL7n
