Re: 6 psi fuel pressure with engine off???
Thanks, Steiner for your insight. This began when I noticed the pressure going to zero with my original mech fuel pump which had a return to the tank. When I pinched the return hose the pressure went up. Upon investigating on this site and the AIM, I found that my engine should have a two port pump (no return) and an inline filter with a return line. But this is only when the engine has a q-jet carb...since my car has a holley, I've tried to use the 302 as a model (small block with a holley). So I purchased an aftermarket replacement from AutoZone. This is the correct pump for a 350/300 h.p and a 302. So, either this pump is squirrelly and the new AC pump will be OK or I have some other problem.
If need be, I'm thinking of putting in the in-line filter with the return...but putting a regulator in the return line.
By the way, the instructions for the pump do not call for a regulator.
Thank you for your advice.
69 SS, 350/300 h.p., M-20, 12 bolt, matching numbers.
