I think the standard setting is only 4psi??
need to run more than 4 psi need to keep fuel bowl from emptying.
Set it on a cold engine, i ran the pump with the engine off. I took my gauge off after setting up and never looked again
The question is - is it keeping the carb bowl full?
I never pissed around with the base fuel pressure to keep the bowl full, I have seen people have all sorts of problems doing this, remember for every pound of boost you add the same in fuel pressure.Originally Posted by LYNCHSTAR
