Replacing a VP44 Injection Pump from Thoroughbred Diesel
Вставка
- Опубліковано 1 жов 2024
- I replaced the dead injection pump and upgraded the lift pump. Thoroughbred Diesel customer service has been easy to deal with, shipping was quite timely and their prices are fair. I have close to 300 miles on the truck as of this morning and everything works perfectly. I should have bled the fuel lines right from the start...live and learn. 1999 Ram 2500 5.9L 2wd 5-speed
This suggestion is too late for the beekeeper but for others watching this video that have a older 2nd gen Cummins and are getting ready to replace the VP44 I would highly recommend replacing the tappet cover gasket on the drivers side of the block. They do get brittle, crack and when they go they make a huge mess and the truck becomes undriveable. You'd end up pulling the VP again to get at the cover. Do yourself a big favor and buy a quality gasket from Geno's or other place. There are some gaskets out there (China anyone?) that won't seal at all.
Happy to see you got that VP44 pump installed and working. :)
So am I, This was a first VP44 for me and your phone customer service sold me on buying it through you guys.
@@yourbeekeeper Yep Thoroughbred is top notch. I bought my Air Dog 100 from them back in April 2016.
@@matticus6339 Thanks.
I would keep 16psi on your lift pump because more psi to the vp44 can damage the front shaft seal on the vp44 .And it will leak diesel into the Timing gear cover dumping diesel in your oil ..
Excellent work! Next time bleed the air out of the filter with the screw on top. And open the injection lines as soon as the filter is bled. Much less cranking required.
I agree completely. Thanks.
Why didn’t he show how to get that cover off to get to the injection pump nut and washer the video jumped right to it was off.
I figured it out, it's just a common thread on it.. Lefty Losey, Righty Tighty
Its just a crank case breather with filter inside and slobber tube coming out the top. Remove slobber tube and turn breather quarter turn or so, should pop right off.
I completely understand motivation on some projects. Took me 6 months to rebuild the trans in the suburban.
haha, Yeah, at least it's done.
@@yourbeekeeper was wondering if you are in the Denver metro, my 99 Cummins is eating alternators? Any helpful tips? Thanks George
I 2nd the tappet cover gasket R&R while in there. I’d also suggest replacing your camshaft sensor which is under the VP pump and really tough to replace with the pump in place. Use OEM part if possible. Thanks for the video !
Great tip. Hopefully that will help the next person.
Still alive, just thought watch so can get ads cents
Nice job, should hold up well.
I think you made the right call. I'm not really a fan of fass. Easy job to do, just gotta pay attention. I replaced my tappet cover with a billet one to prevent leaks.
THanks Alan.
Over 150K on my FASS working flawlessly. I hear mixed reviews but I’ve had them on different truck with high mileage and no issues at all. Using fuel gauge to tell me when a filter is needed
@@phendrix9476 304k on the lift pump in my 97 12v. Cant beat mechanical pumps
No easy job. Looking forward to see how well it performs you.
Thank you, Time will tell...but so far it's been rock solid.
enjoyed watching the video. The truck I just bought has the Raptor lift pump already on it. Been thinking about getting the glowshift gauges but dread having to install them. I do have a fuel gauge on top of the fuel canister reads 22-24 PSI. Had to replace a power steering hose which was leaking at the crimp. Keep them coming. thanks
Thanks for watching. So far I really like the glowshift gauges and they are still working just fine. My only complaint is they don't have much dimming capability. There is a slight reduction in brightness when you turn on your lights, but they are still very bright to me and distracting. Just a small gripe, but I spend a lot of time on the road at night and the A-pillar gauges are right in my field of view. The red background or the deep purple background are the most comfortable to me at night. I have a video on my channel of my installation of the gauges...it's not too bad really.
I really like my 2002 3500 too. I've owned 1st, second, 3rd and 4th gens but I like the second gens the best. Another thing I do is in the summer when it's hot is keep the fuel tank above half a tank when I'm working the truck like towing hauling hay or cattle. The pump is cooled by fuel and if it's hot outside and working the truck all the fuel returned to the tank just keeps getting hotter and hotter if I'm thinking right. More fuel the longer it takes to heat up.
Ive got mine tore apart waiting for one more seal. Started leaking on rear seal of trans and small leak on input of dif and little seepage on transfer case so u joints and seals all around while its apart. Also carrier bearing. I'm 63 so it's a two week project. Little at a time.
That's great info.. Thank you for that.
Reminds me of replacing a 5.9 in a Gradall G3WD about 15 years ago. After we got the engine in and it went back out on the road, the injection pump worked loose, and I had to tighten bolts on a very HOT engine. We had to repair it while the engine was hot, as the crew had the road cut to replace a culvert and didn't have another piece of equipment that could do the job. I had scars on the back of my hand where it was blistered. I only wish I had had the room that you have on your truck.
I have replaced a couple IP's on tractors and I agree...the clearance is nothing like this one. My hands area also a road map to past work and makes for good conversation...haha.
That's a good way to burn up a starter, sounds like air in the system?
Nah man, as long as you don't crank for more than two solid minutes should be fine. They are made to do lots of cranking and heavy cranking..
However you were absolutely right, there is air in the system and it will never fire with air in the system.. the vp44 is not a self bleeding system.
I believe the p7100 is, and I believe the CP3 is... But not that little guy.
Hey, brother... I replaced IP and lift pump on my 2002 3500 last year. I also have the same gauge kit as you. I've done tons of research on lift pump pressures and here's what I've learned... 20 psi is MAX. 6-7 is MIN under load. 14 psi is bypass pressure (return to tank). So above 14 psi the IP is getting fresh cool fuel even when the engine isn't consuming as much fuel as the lift pump is providing. I see 19 at idle, 14 to 17 during normal driving and never less than 10 under heavy load with Fass DDRP ( similar to your new lift pump). Based on what I've read this is pretty much ideal. Hope this helps
That's awesome!!! Thank you Robert, That puts me in a good direction. I will turn it up a few pounds for sure.
No problem... my truck is pretty much stock as well. The only real difference is I have the 6 speed manual. A VERY good (probably the best) resource for info on these trucks is Turbo Diesel Register (TDRonline.com). They ONLY cover dodge diesels and have the support of a dedicated and knowlegible community. Thanks a ton for the videos... Looking forward to more
Great Video !!
Just trying to diagnose My 99.
At 80 k, replaced VP-44 and put on an Air Dog Lift Pump.
Now at 98 K. And much time parked had some slow starts, didn’t run at all for 2 mos. it will not fire. Fuel 3/4 tank fuel at front banjo on pump. No fuel up too. Loosened 1,3,&4. A little out of 4 still not starting ??
All indications, new Pump ??
All suggestions considered !!

Hey Steve, I want to wish you and yours a Very Merry Christmas from Honolulu! I am so behind on your videos. You are one talented person.
Keep up the super great work. I wanted to send this in a private message but it appears that You Tube removed that option.
Aloha and stay warm my friend!
Hey Clay, Hope you and your family had a Wonderful Christmas. Yeah, they removed the private message feature a few months ago...not sure why. Aloha!!
My raptor crapped out on me and they told me it was because I mounted it in the stock location (like instruction tells you to do) and it needed to have a draw straw installed in the tank. I got a refund and bought a fass pump but I did mount it back by the tank and I put the draw straw kit in. I almost bet the stock lift pump burnt out your vp44. My fass pump won't drop below 11 psi at wot and runs at idle 17 psi at 60-70 mph 14 psi. I guess they say 7 psi is a safe min. but 10 psi would be in my opinion the best min and not over 20 psi highest. I hope my vp holds up I did put injectors in it and it cleared the warm engine skip it had.
Oh boy... I hope this Raptor doesn't give me issues...ugh. When I bought the truck the lift pump was dead and it was crusty and likely dead for quite some time. I didn't realize it until I installed a fuel pressure gauge. I was very new to Cummins and didn't know what I didn't know. I knew I was living on borrowed time. Thanks for the pressure information, I'm planning to turn up the pressure a few PSI and have it sit at 17~18 at idle. There is a lot of conflicting information out there....I have read 6psi~8psi as absolute minimum and at 14psi is where you get the return flow of diesel which is best scenario to keep the IP cool. So far, I have about 7k miles on this repair and it has not missed a beat. Time will tell.
To understand the Cummins fueling there is both pressure and flow, the flow is very important because the VP44 is cooled by the lift pump, so you need plenty of flow. Your fuel pressure should be 15-18 psi and is normal to drop as low as 10 psi under power, just because the pressure is dropping does not reduce the flow per hour unless it goes below 10 psi.
Where did u get ur kit from for the lift pump?
Thoroughbred Diesel.... it's in the title, it's in the description and I talk about it in the video a few times.
Nice work man. Patience is key
Yeah Buddy... Thanks Brayden.
where did you get the box for the bhaf ?
I built it myself. Here is the video. ua-cam.com/video/W4vYxLy5jQU/v-deo.html
👉💥👈👍
I thought we would see the P pump conversion with 150hp injectors with the new twin turbo set up lol. Did you ask Wayne if you should do the injectors? They are the originals no doubt.
Cut it out!!!! keeping this one stock and reliable. hahaha Wayne says these mechanical injectors rarely fail and should be fine.
great job a bit of fine-tuning is all you need thumbs up and shared im not sure what the specs are but a bit of research im sure you will find out fast
Thanks Drew!!!!!
Manbearpig is real, he's half man half bear & half pig!
Hi I came from dieselstop but where is he at is he alive why is he not made videos anymore sry I’m a long time subscriber to him
Wayne is doing well, He doesn't make videos by his choice...sometimes the urge to make, edit, upload and manage videos fades.
Nice job, should hold up well.
Is the vp44 still running 3 years later?
Yep. It's still running well.
I replaced mine with a 24mo warranty one. My truck feels slower. Did you experience that?
im currently trying to change my vp44 on my 2002 dodge cummins and im trying to take the front bolt off of the pump but everytime i go to break it the whole serpentine belt and pulleys move so it just keeps turning and not breaking what should i do
If you haven't already figured this out, I would use an impact wrench (air or electric) to get it off. Best of luck with your repair.
Little late to the response but for future reference take a 7/8 socket and put it on The alternator nut. The belt will slip clockwise so hold ratchet counter clockwise and that will stop the engine from turning over while breaking the nut loose. Also helps when torquing the nut down. And is a huge help when doing valve lash! No more getting under the truck and turning the engine over by crank pully!
I sure luv mine dash is shit.
What size raptor pump
100 gph
Good video ! God Bless !!!
Thanks William, Appreciate you watching.
Where'd you get your Intake housing from? I have the same filter. Thanks
If you're talking about the enclosure the filter sits in...I made it. Check out the video of the process. ua-cam.com/video/W4vYxLy5jQU/v-deo.html
When I installed my raptor lift pump it made 18psi at idle and 13-14psi at wot,
That's good pressure. I never messed with the pressure screw from factory, and now that the pump has some miles on it, it has settled at 16-17 at idle and 10-12 at WOT. I am going to turn up the pressure up a bit to keep it at 14-15 at WOT.
@@yourbeekeeper yeah I never touched the settings that was factor set and has maintain that for 3 years, but the vp44 just died it was long due tho
Nice work!
Thank you Jim.
What gauges do you have on your truck?
I installed GlowShift gauges. Here's the video of that installation. ua-cam.com/video/AJ4POEakmLA/v-deo.html I sold this truck in May 2020, and everything still worked well and I was happy with them.
To many parts, looks like a gd nightmare to install...
Honestly it's not that bad!!
On a scale of 1 to 10.. I would throw it probably right in the middle!
I don't know about the lift pump but I couldn't imagine it being any more in-depth than changing the IP? I mean shoot the IP is generally in the way when you go to change the lift pump, so you have a lot more direct access to it.
In Cummins world.. this is a pretty in-depth installation, but I find the worst of the worst on Cummins, is a joke to most other vehicles... What cost you is the money for the parts!! Nothing cheap.
What kind of air filter kit is that?
It's not a kit. Here is the video with the information. ua-cam.com/video/W4vYxLy5jQU/v-deo.html
Aweeee... Lol I was hoping tuner!
Oh well, this is probably the choice I would make! Haha
I would like to know why your intake horn is so discolored??? Lol
Mine look the blackish before I cleaned it, why is yours Brown like it was left in the oven too long? Lol
Damn bro you're absolutely right... Crack a couple injection lines 😳
Edit -
1 3 & 4!!!
Also just crack em loose dont have to be all the way!!!
Overall / better than half the special Ted's I've seen do this.. I've done it a hundred times myself but you still got to look back and say you started somewhere! Haha.
I have a Superchips Tuner for this truck. It's a work truck not anything built for speed, so it works for my needs.
The previous owner said the grid heater relays failed and stuck on...almost burned the truck down. I had a fleeting thought to paint it or try to wire wheel and re-clearcoat that horn... but with the hood closed, it all looks the same to me...lol.
Nice work!
Thank you Sir.
Please say you changed the Injectors too!! The injectors can sometimes cause a pump to fail as they get bad and don't allow normal spray.Also before i would fit a new pump i would change all diesel lines back to the tank and remove and check complete tank especially in a truck of that age it would be insane not to do all that.
are you still happy with the pump ?
Charles Boston Yes. I have put just under 10k miles on the truck since this video and it hasn’t missed a beat.
