Hello all, been a long time since I posted.

 

I am finally getting around to the finishing details on my EA-81 (w/EA-82 intake) swap into my 78 Westfalia Campervan and I am using a Weber 32/36.

 

My question is, what PSI fuel pump should I use (w/ a pressure regulator)?

 

There are two types, 2-3.5 PSI and 4-7 PSI.

 

What do you guys and gals use?

 

Thanks!

With a regulator, I would use the 4-7psi. No sense in potentially under-fueling it, although with carb setups volume is more important than pressure.

It's easy to dial down your fuel pressure w/a regulator, it's harder to replace a pump to raise it...

we used 2-3.5 PSI fine too

I seem to remember the spec for the weber carb being around 3.5-4 psi. I would also recommend using the higher pressure pump and bringing the pressure down with a regulator. That way, you can play around with different pressure settings and see where it's happiest.
