Question how big is too big?

im in need of a new fuel pump (i think) anyways after the car sits for a few hours you have to cycle the key for it to start...and the fuel pump runs o.k i guess, but it will just crank and crank then finally start.

is the 255 to much for the mods i have...i plan on going with the 224/230 in the future and some long tubes to go with it, and some svo 30lbs injector.

thanks for you info.

steve

Its more than likely your bleed back valve. Unless you're having problems with stutter at high rpms. You may be able to save yourself a lot of time and headaches, as well as money...

No... A FPR (Fuel Pressure Regulator) Regulates the fuel pressure throughout the RPM band. A Bleed Back Valve prevents gas from "bleeding" back into the gas tank. Therefore preventing the need for priming. Thats all the info I have on the subject.....
