will you check to see how long it holds pressure when you turn the key on, then back off? I got a 255 from houston performance, and noticed that if I turn the key on, psi goes up to 35 or so where it should then back down to 0 in less than a second, regardless if I leave the key on or not. HP said it was normal for the 255s to bleed off pressure like that :bs: . I think I got a bad pump and the return line check valve is screwed up and stuck open. I have no external leaks and no smell of gas anywhere, and thats way too much pressure to bleed out through the injectors in 1 second. It's also making it harder to start, but once it is started, it does hold the pressure where I set it.
