performance fuel system ?'s

i have the stock leaking cam driven fuel pump... hard to get to and ive replaced it twice... what kind of fuel lift pump pressure does a OBS 7.3l need? is there any advantage to putting more pressure to it than stock? im planning on running some 160cc or so injectors will extra fuel supply be necessary? i dont want to stomp the pedal and run out of fuel...

Spec pressure for these trucks is 65 psi. I think one shouldn't exceed it, since it could cause injector o-ring sealing issues.

i see... well ive been away from the good ole 7.3 for a couple years now.. does anyone make anything like a larger fuel rail? or something similar to oversizing the cummins' injection lines where flow volume is increased? will the head have to be modified to fit a larger fuel rail?

The best way to go is with a complete kit, unless you think you can do it yourself. Swamps makes a couple of nice ones as well as diesel stop depending on what you plan to do with the truck. They both maintain about 55psi with a regulated return. There is a couple post on here about the DIY regulated return kits that are good. Good luck, it'll be well worth it even stock you'll notice a better idle and throttle response.
