Most Popular Questions

How do I adjust the fuel pressure on this pump
View Staff Answer 
The FASS FA D08 165G Adjustable 165GPH Fuel Pump is normally pre-set by FASS so it's ready for installation. However, if you need to adjust the pressure you can do so by loosening the lock nut on the top of the pump, then turning the adjustment screw clock wise to increase pressure, and counter clockwise to decrease. Once you get your desired pressure, tighten the lock nut and you'll be good-to-go.
