Lift pump question.

X2 on doing it right. I put a block mounted on to run with my failing in tank pump when I first got he truck. 32psi at idle (WAY too much), 18 cruising, and 6 to 8 or so at WOT. It got me home, and was replaced with a FASS150 shortly. I wouldn't be surprised if that 32psi damaged the internals of my VP44.

NO! at a mininum I would put on a fass ddrp that will outperform the stock lift pump,there is a fine screen to cleaned on the input side of the pump,a bit of a pain,There are other options,a much bigger fass,airdog,raptor,etc.You do not want 5-6 lbs fuel pressure on these trucks you want more! nothing under 10psi@ wide open throttle.If your going to do other mods to the truck go with a bigger pump. Put gauges on also pryo,lift pump pressure,boost, then go from there

Thanks I will! We installed a DDRP on my uncles 2001 dodge back in april and its been great! He has a BANKS tuner on it and it still holds great fuel pressure, he loves it!
