The FASS Adjustable Fuel Pump FASD02165G is an electric lift pump that bypasses the factory mechanical transfer pump on the first-generation 5.9L 12-valve Cummins. It supplies the factory filter housing with consistent pressure so the VE injection pump is never short on fuel.

This 165 GPH version is recommended for moderate to extreme horsepower builds. Pressure is preset at about 8 PSI and can be adjusted with the pump's adjustment screw and lock nut.

• 165 GPH Flow: Recommended for moderate to extreme horsepower 12-valve trucks.
