fuel pressure problems

My dad's 98.5 truck had the injection pump go out on him. $2500 later, new pump installed and he put in gauges. Taking off from a stop his pressure will fall below 6-7 psi. From what we've read it sounds like his lift pump is shot.

My question is this. Stock replacement pump is about $200-$250. He is looking for alternative (cheaper/improved) sources to replace the LP.

Will the "black holley" fuel pump work for him? From my research, all he needs is a 14-16psi @ 100gph pump correct? These holley pumps through jegs are $120, alot better than $250.

As for a Holley black it should work. You might have to use a regulator. I know a lot of people are running holley blues...

As long as you can hold pressure above 10 PSI at WOT you good to go!

FASS is not required for <450-500 HP trucks...

I would say get a big line kit while your doing the pump upgrade and get it done right the first time.

01 quad cab 4x4, edge drag comp, 4" exhaust, fass 150, 250 ddps, Jefferson State compounds 683hp so vp 11.91. AMSOIL front to rear. now back to stock 95 fummins in the works

fass is kind of a over kill for light modified truck or stock but thing is with holley or carter pumps they can fail then you have to buy a new one. with a fass you get 6 year warranty no need for regulator plus u have the option of getting a 2 micron filter which is alot better then a 10 or 7. spend the money and get something that will last and u dont have worry about. dont be cheap now i could coast u another pump.

now own 2007 5.9 6 speed afe stage 2, ppe programmer, 5inch silverline turbo back

traded it in 01 dodge, dual disc, drag comp, head o ringed and studed, stock turbo
