Re: holley fuel pressure regulator problems
heres the problem, the tbi in the tank is way too much pressure for a carb. I had same thing. theres only 1 pressure regulator that summitt racing sells I think its a mallory that will regulate from like 35-40 pounds down to 5. its around 100$ or more. what you can do is get a holley blue or red electric pump, or use a mech pump on the side of the block w/ your regulator.it sounds like you drive it on the street, any street carb should'nt have no more than 5-6 psi. check your floats while @ idle. I left stock pump in tank and pulled the fuse to the pump. and ran a mech pump.since than I bought a holley red pump/ reg but have'nt installed it yet.
