The FASS Adjustable Fuel Pump FASD02100G 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 100 GPH version is recommended for stock to moderately modified trucks. Pressure is preset at about 8 PSI and can be adjusted with the pump's adjustment screw and lock nut.

• 100 GPH Flow: Recommended for stock to moderate horsepower 12-valve trucks.
• Adjustable Pressure: Preset near 8 PSI with an adjustment screw and lock nut.
• Inline Suction Filter: Included inline filter protects the pump gears from debris.
• Works With Factory Filter: Feeds the factory filter housing on the engine.
