LostWater Posted January 29, 2007 Share Posted January 29, 2007 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!

88RxTuner Posted January 29, 2007 Share Posted January 29, 2007 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... Link to comment Share on other sites More sharing options...
Carmen Posted January 29, 2007 Share Posted January 29, 2007 we used 2-3.5 PSI fine too Link to comment Share on other sites More sharing options...
Snowman Posted January 29, 2007 Share Posted January 29, 2007 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.
