I am putting an Edge COMP on my stock truck and my fuel press now is 12 at idle and 9 WOT... do i need an additional LP??? and if i do, what kind should i get?? thanks, Awall

 

9 psi at WOT sounds ok, but if it starts to get lower than that, I would get a FASS System. You won't have any more Lift pump or fuel pressure issues after you get a FASS.

 

how much is the FASS system?

 

Here ya go.....

All you would need is the following:

FASS 95/95-1008
OR
FASS 150/95-1008
OR
FASS HPFP-95-1002

 

thanks, awall

 

mine was the same 9psi WOT, comp came I could get 4-5. fass is WAY to pricey for me so I used a holly black pump and fleetguard waterseporator prefilter, (kind of like a fass) for a whole lot less. now I cant get less than 15 WOT

 

If you're seeing 9 WOT stock, the comp will pull it way down. You definately need to upgrade before you tap the wire. Search "Walbro" as a great and much cheaper alternative to the fass.
