I was a bit scared to try and figure out the wiring for my electronic fuel pump on my bus and this video really helped me out! The toggle switch is definitely the right move. Now on to plumbing the fuel lines!
Awesome! Did the same thing and love the performance! Just so everyone knows, my mechanical, original, fuel pumps diaphragm failed and gas leaked all in my crankcase/oil. What a mess that was! After much research I learned the Carter 2.5-5lbs fuel pump was the best way to go. They’re on Amazon and still relatively inexpensive($35-40). Well worth it for the peace of mind. Definitely want to install a kill switch with it. You never know! Takes a little time but, again, well worth the efforts.
Yep. I do appreciate the genius utilitarian aspect of the mechanical fuel pump, but over all, electric fuel pumps have won me over. You know the rule though….gotta get a spare to keep around LOL!
Thanks very much for the video. I like your presentation style and I really like your bus! I got one of these electric pumps on the way in the mail. I also ordered the oil pressure activated cut-off switch and I'll see how well (or not) that works.
Glad you found a pump. Want to get one for my Bug too but that pump has become hard to find and pricey. The one in that video still works like a charm though. Good luck with your install.
Man , I must have bad luck ! Had two Carter fuel pumps fail on me , bought USA made low pressure FACET pump never failed . Recall using these since the 80s and no fail . I'm sticking with these .
That is good to know because if and/or when the Carter fails me, I probably won’t get another one $$$$. They became quite proud of them and the price is ridiculous. I got two Derale pumps cheaper than one Carter for my Bug, so I even have a spare. The Derale was noisy at first but seemed to quiet down after break in (or I got used to hearing it). Good to know about the FACET though. I saw those but wasn’t sure
I had a problem with some Weber ICT 34’s like yours, because they were letting fuel down the manifolds when the bus wasn’t running. It would then seep past the rings. I then had a lot of fuel In my oil which made it run crappy. If you are still getting fuel in your oil try rebuilding them carbs. Great video though.
So even the Webers do it then 😎 You are correct. I rebuilt both carbs and found the needle valve gaskets were both incorrect thickness, and crushed. Thanks for watching!
Sweet. Gonna go with the derale pump. Aren’t those considered rotary pumps? Or are only the Carter rotary? Any ways I like the set up. Buying a derale and block off plate from cb performance.😁
I haven’t kept a close eye on the actual temp numbers, other than acceptable ranges. I’d guess that with all the benefits of proper fuel delivery, better temps are possible. That particular fuel pump is still running strong, but always good to keep a spare on board. Have fun with the ‘81!
Did you ever add a pressure regulator on this bus? I'm wondering if my pump is pushing too much gas and getting past my needle and seat. I just replaced my floats so gonna see if my gaskets stay dry on the carb. if not I think I might have too much fuel pressure. I put the same one you have.
Not on the Bus yet but need too. I do feel like it has a smidge too much pressure, just not as much as other fuel pumps allow. It will allow a small amount of fuel drip onto the butterfly sometimes. I’d like to get another Mallampatti fuel regulator and some Weber hardware for it.
I admit that I haven’t checked the pressure with a gauge, but I also don’t trust the gauges I have. When the Bus ran way better and the carbs stopped leaking, I just chalked it up as a win. I did buy the 2.5-3psi pump though.
Great video. Have you noticed any change in oil pressure or performance after removing the rod below the fuel pump? I am about to change to an electric fuel pump and cap it off but heard a coupe different things. Thanks!
I’ve had zero issues with oil pressure. As far as performance goes, I saw an improvement to cold starts, along with smoother running at all RPM, and engine returns to idle well. I feel that The carburetors demand a specific pressure to function properly, and that pump provided it. I have I’ve installed one on my ‘65 Bug since that vid, also with no problems. To me the downside would be failure of the electronic pump could be more likely than mechanical one, but I keep a Derale pump as a plug and play spare. Good luck to you!
The relay I had there was a NOVITA RL45. It has 5 prongs but you really only need a 3 prong relay. I ran a wire from a “switch on” fuse (eg. Ignition fuse) to a toggle switch. Then another wire from that toggle switch to relay prong 30. Then a wire from relay prong 87a to the fuel pump. Relay prong 85 has a wire going to vehicle ground. Again, you don’t need the inline toggle switch for this to work, but I like it. I am not an electrician. This is how mine is set up and I’ve had no issues. I’m sure there are better ways. 0504BD 18310 was the pump ID. I got it on Amazon, but since then have not been able to find them (except for at JBugs, at a very high price). I’ve heard that RockAuto has them now too. With that said, I’ve also put a different brand pump on my 1965 VW Bug that is way cheaper in price, but very reliable (it’s noisy though). My 1970 Bus still has the same pump that’s in the vid and is still strong. Hope this helps and good luck🤙🏼
Awesome. But is there a need to install a switch? When I installed an electric fuel pump on our VW Bus, I did not install a swtch. Do I have to install one? Thanks so much in advance for your reply.
No absolute need for a switch at all. I use mine for: 1) There are times I like to run all of the fuel out of the carbs, so I turn fuel off with switch and let the Bus run it out. 2) Bus door locks don’t work so if I’m parked out on the town somewhere then I turn the fuel switch off...a potential thief shouldn’t get far. 3) I know a guy who wrecked his bug, had a fuel leak, and couldn’t turn the car off at the ignition switch. These are my reasons, but not a must. I’m still liking this fuel pump👍🏼.Thanks for watching!
@@bomberobus Thanks so much for these reasons and I know having a switch gives more reasons than explanations. I am considering of installing a switch too! Thanks again!
I guess if you provide an email I could draw up my schematic? The fuel pump is a “Carter” from Amazon that was specifically advertised for Aircooled VW’s. The relay and switch came from Autozone. Hope this helps. I’m new on UA-cam but I’ll try to add links in the description soon. Thanks for checking it out! 🤙
Yes, and it is the ONLY electronic part I’d recommend. I drive mine a lot, with good distance, so I tend to keep it simple, except for running a bigger engine (for safety). The one in that vid is a Carter and is cream of the crop, but I run a Derale in my bug. Whatever you choose, get two, keep a spare on board for easy plug and play in a pinch. The cheap mechanical pumps today are pushing way too much pressure. However, they are ok if using a really good fuel pressure regulator like a Mallampatti. I just don’t like where they’re located because I vent my case from that spot instead.
The fuel pump runs off the distributor gear, I don't see how removing it could affect oil pressure. Where did you get the accelerator cable return spring
The pump is still running strong and has not affected oil pressure. The spring was already on that engine, and I suspected it to be an old pressure relief spring.
@@bomberobus I'm on my third mechanical pump failure. Two flat out stopped working and one leaked into the oil. I'm going with an electric one. Aftermarket parts are absolute junk these days.
Agreed. I appreciate the mechanical pumps, however, they aren’t made as originally intended. I keep an extra pump onboard in case of electronic failure, but haven’t needed it yet. The price/risk of fuel in the case via cheap mechanical pump isn’t worth it to me. Good luck moving forward with you fuel pump!
Offer I couldn’t refuse on the engine, so sold. Kept the tranny in hopes of putting it in my ‘70 bus with a bigger engine one day. Roof has rust holes beyond my scope of repair, currently. Ultimately, I hope to slap one of my good running type 1 engines in it (after building a bigger engine for the ‘70 Bus) for just using around the property. I have thought about just cutting away all the bad metal and just having a crazy open cab surf bus, but life 🤷🏻♂️
Hi Friend. I just started to reconstruction my VW Bus 1978. so I have a question do you know how to conet or intall these hoses for the servo booster break system?....thanks for read my message. Im Jaime from Houston, Texas
Sorry Jaime. I do not know at the moment. Although I have 77 Bus sitting in the barn, I haven’t gotten around to working on it except to bench start the engine. I hope your restoration goes well…there’s something special about a Bus!
Amazon, but can’t find it anymore. JBugs and Aircooled.net has them now but priced high. I recently bought 2 Derale pumps for the price of one Carter. Put one my bug and another as a spare. The Derale works great but is LOUD Whichever you get make sure it’s 2.5 -3 psi
I was a bit scared to try and figure out the wiring for my electronic fuel pump on my bus and this video really helped me out! The toggle switch is definitely the right move. Now on to plumbing the fuel lines!

I like that extra switch, some added secret security.
😂 yes! They might get it started but wouldn’t get very far.
tks , super kool job to do on my 86 bus.
Yeah man it’ll be sweet but you know the drill….snag a spare one too😂

Pretty sure the Derale is just an in-line pump and not rotary
Great Video, thx!
I wana do the same on my T3 81 air cooled Bus. How about temperature, getting better with this (lower temps)?
I haven’t kept a close eye on the actual temp numbers, other than acceptable ranges. I’d guess that with all the benefits of proper fuel delivery, better temps are possible. That particular fuel pump is still running strong, but always good to keep a spare on board. Have fun with the ‘81!

Nice job on the install.. did you ever test the fuel pressure? The Carter fuel pumps come in two different psi’s

@@bomberobus can I get the parts list too? This video is great. Also, I’m new to wiring. What gauge wire did you use and what relay did you use?
Do'nt forget to fuse the pump power leads.
Great content being that it's 2 years old . Would you still recommend the electric pump over the mechanical one

What kind of fuel milage does it get being air cooled? Let's hear it run!
Round about 24mpg. She’s running strong in a lot of vids💪🏼

Did you install a fuel cutoff relay also?
With a switch

Definitely no change in oil pressure
What kind of relay ?
Just some 12v 40amp 4 pin relay from autozone connected to a toggle switch
