adjusting fuel psi on fass 150

[blowinsmoke]

I've seen a thread about this but cant find it- does anyone know how to increase the fuel psi on the fass 150. It's about 2 years old so its one of the loud ones. mechanical gauge says 10psi all the time but i think it should be around 20 at least

Change the bypass valve spring to a stronger one to increase pressure.

Where do you get a stronger spring? Contact FASS??

This only applies to the 150 Series FASS systems:



PS-1001 -- 8 PSI

PS-1002 -- 13-14 PSI

PS-1020 -- 19-21 PSI



Any FASS Dealer can help you with obtaining a spring for your kit.



Now for the 95 Series FASS systems:



PS-1007 -- 6-8 PSI

PS-1008 -- 12-13 PSI

PS-1001 -- 16-18 PSI



I would still double check your gauge... ... just to be sure... ...
