LB7: Fass Platinum 150 fuel pressure

[MechanicalReign]

I have a Fass Platinum 150. I recently hooked an fuel pressure gauge inline just before my FICM. Its only reading at 5 psi and drops to 1 psi at wot. I need to find out if theres a way to turn the pressure up on this pump? Cant seem to find much info on the Platinum pumps besides install instructions or if people like em or not.

Thanks bud! And to try to answer your question the pump it's self isn't adjustable you would have to buy a need regulator but I heard of people changing the spring to up the pressure

that sux I couldnt see the regulator helping unless i was having to much pressure. Guess Ill rock it like that for a wile. Is it possible to add another pump after it that dont have filters to get the pressure or will it mess with the fass?
I would like to know more about this spring and if it ups it to much then have an regulator

I may be wrong but as long as your holding some pressure at WOT I think your good, even if its only 1 PSI ???

Any positive pressure from 0-15 psi will keep a stock cp3 perfectly happy. If you had a lift pump that supplied a constant 1psi at wot or one that supplied 12psi at wot the cp3 won't know the difference. However the if you're using the factory fuel pickup in the tank that is probably your reason for the pressure drop.

yeah its still factory pickup. Thx for all the info. Ill try a different pickup when I go efi live. I have a feeling it might want the extra flow

last question. could i loose some pressure with having an 0749 cat filter sence its so big and 2 micron? I have the sensor after it. I Wouldnt change it just wondering.
