Aussie Dubbin - November 29th, 2011 at 06:54 PM

Hi Guys,
car was having isses getting fuel to carb sourced it to a broken spring inside the old fuel pump donated off a 1500 motor. (motor in bug is 1600now out of 72).

Question: buy new fuel pump replacement or electric...?

What are you all doing?> if i buy an electric pump do i need a pressue reg too? I know that i will have no probs just buying a standard pump. BUt is an eletric much better... i will prob go webers soon enough so thats the issue???? Cheers

elec pump would be ok but an replacement would be good to really up to you price etc and you wont need a regulator
happy dubbing

I have always had an electric pump in My beetle...

its a black plastic round pump... located under the fuel tank
with a dash switch and light to tell Me its on/off//
[I also have a new spare]

I did have a problem a couple of years after installation with flooding so, I fitted a fuel pressure regulator and then a fuel pressure gauge...

You only need about 2 PSI of pressure for standard carbies..
and most electric pumps will go to 5-8 PSI.. or MORE
which is all You need.. unless You were going for Fuel injection..

cheers

PS- I believe all cars have electric fuel pumps these days..

can't find pic of fuel pump...

Best way to go.
Stock pump is the old K.I.S.S solution.

stock pumps will keep a huge IDA engine fed, don't need regulators, wiring, rubber mounts etc etc
Just keep an eye an the pivot pin, most new ones don't have circlips and like the spit the rod out.

Electric pumps just create too many other problems, wiring up a safety system so they cut out in the event of a crash or if the engine stalls, regulating the pressure, the cheaper facet ones don't cut the flow when off, so park uphill you may get a sump full of fuel, they are noisey etc etc....

That's cos they are all fuel injected.
You'll find 95% of carbed cars even 90s ones all have mechanical pumps originally.
The last new car I drove that was carbed was a 2001 Mitsubishi Express van and it had still had a mechanical fuel pump.
