Electric Fuel pump question
Advise needed. I am after replacing the standard fuel pump on my 1776 t3 motor with an remote electric one. The reasons being....
Not having a pump in the engine bay seems alot safer and less chance of an engine fire
Added security as i will have it on a hidden switch and the car won't run if started
Bigger , thirsty carbs ( 44's ) will need a good flow of fuel
I'm thinking of mounting it either nearer the gearbox area or on the rear inner guard with a natty cover over it.
Heres the questions.
Once i take off the original fuel pump what and how do i use to blank it off.
What electric fuel pumps are worth thinking about and how much $$$$
Many thanks Dan

you can buy a cover that fits the old fuel pump area
As for your fuel pump , there is some shit ones out there so get a quality one .the off road guys would know whats best .
I would keep the old fuel pump and some hose & clamps , just incase the electric one shits its self .
I have a holden camera fuel pump and pressure reducing valve on mine .The pump works very well . I got it from pick a part for $15.00

I have a plastic fuel pump located under the tank at the front.
with a switch and light... on the dash...
I did have to get a fuel pressure regulator [holley] as there was too much pressure for the carburetors needle & seat....
Neils way is very cost effective.....
Mine cost Me over $100 on ebay...
I also found another pump identical to the first one at Home still in its box that I must have bought prevously....
so Now I have a spare....
My Son had a Mitsubishi electric fuel pump on His Beetle, I don't know it came from, wasn't new... went for about 5 years before playing up for a
few weeks-- before being replaced, so it didn't just stop .... had to switch it off & on until the tick tick could be heard.... then it would be
OK....
I made a blank off plate from aluminium... then I used it for a breather hose, now I'm going to have the oil filler going there... so I have to make
a plate from steel so it can be welded...

Sorted!

No I'm keeping the spare pump....
they do pop up on ebay quite frequently...
The round black plastic one I have is a common after market pump... sold by Auto electricians a few years ago...
They are sold by brand name in the US but cannot remember what it was.... I believe they are a rotary pump... [?]
There are also Holley electric pumps etc....

Few Q's
This is my understanding......
From fuel tank i add an in -line filter then onto the electric fuel pump. From there it uses the standard fuel line through the car and then goes into
a regulator , then a T piece off to the carbs.
Few Q's
Where do i mount the fuel pump?
Can you get solid lines for the carbs? Rather than have a T piece with 3 connectors?
Cheers Dan

I just picked up a brand new stainsteel cased carter pump. Cost me $120. it comes with a pressure regulator, of 2 to 6 psi, but i will use an
adjustable malpassi one. i forget the flow rate, btu worke out i would need to chew through a tank of fuel in under 45mins to reach teh pumps limit.
I have no sympathy for my car, only the wallet that pays for it!
Go hard or go home!!!!

Most pumps will chew thru a tank of fuel very fast thats why You need the regulator...
The best place for the pump is under the tank.. IMHO...
and put a switch under the dash so You can switch it on & off at will... this comes in VERY Handy if You have an engine fire.... Just switch off
the pump and the fire will go out....
I hope You still carry a Fire extinguisher just in case...
Any chance - a photo of repco pump etc... any photos welcome...

I used a combination of 3/8"ss tube and ss braided hose for my install. Check on ebay for plenty of reusable ss flexable lines, consider buying the
fittings on ebay as the new price is sky high.
I mounted my Holley fuel pump and filter just under the tank.
I found the Holley quite loud, and I think I would run the regulator on a return line to the tank just after the pump. This will ensure that at idle
for long periods in high ambient temperatures that the fuel temperature does not get too high and result in vapour lock at the pump which happened to
me during a very hot day recently. This should also take some load off the pump I think? You will most likely need a fuel pressure gauge after the
regulator to ensure that fuel pressure is correct as well.
Just use a cheap electric pump from a VL Holden and run a suitable regulator.

Try a good ol' Subaru electric pump. They have automotic pressure control and are designed for carbies, not fuel injection, so the needle and seat
regulate the pump beautifully. I run one on the buggy, and it's quite happy...
And they're cheep too...
On top of that, if you do run into trouble with it in adverse conditions, you can pull them apart easily and fix them on the spot.

Don;t forget to have a fuel filter under the tank so no rubbish can enter the fuel pump...

Danny,
Good to hear the project is ticking along.... I love the type three shape that you have..did you get a set of wheels for it?
Oh, you can get hard line from autoparts shops...motorsport connections seven hills is another. You will still have the joins at the T piece though,
so braided is probably the best for peace of mind.

What pressure does the Subaru electric pump at?? And can the pressure be altered at the in built regulator? |

You can get the braided steel fuel line from Mick motors at $12 a metre.... I used it on My installation too....
I used hose clamps, but with the steel braided hose its very very difficult to get off barbed fittings...
and use at least two hose clamps where the hose attaches to the original fuel line... where there are no barbs....
Have Fun....

Um, although I think you're all talking bugs, a dude up at Coffs told me something I found useful, regarding electric fuel pumps.
Well, they have no valves inside right? At least, some of them don't (new ones? Not sure what kind of pump they are... Some rotor-impeller I
guess.) That means that fluid can flow through with the pump switched off. This is not the case with a diaphragm or piston type one (right?).
Now this is relevant to a Kombi, because of the layout of the tank and engine. Apparently, it is in some cases possible to siphon out the fuel tank
through the elec' fuel pump and carbs, say if you parked on a hill or something. (Like overnight, say). Might be an unpleasant start to a
morning!
So, I was advised to run the fuel line through the old stock mechanical pump as well. I don't know what the procedure here is, but
the point is that you want some proper shutting valve somewhere to eliminate the chance of siphoning fuel. The mech' pump will do that.
I don't know about details, but I see the in-principle argument here.
Cheers folks,
Aurel
(electric fuel pump, kombi, fuel line, siphon)
