FLEECE POWERFLO IN-TANK FUELLIFT PUMP FPE-34790 | 2007.5-2010 6.6L DURAMAX LMM

Upgrade the fuel delivery system in your GM 6.6L Duramax LMM with the Fleece Performance FPE-34789 PowerFlo Lift Pump. Designed as a direct in-tank replacement for the factory pump, the PowerFlo provides increased fuel flow to support applications producing up to approximately 800 RWHP while maintaining a clean, factory-style installation.

The PowerFlo utilizes dual OEM-quality gerotor pumps for increased flow capacity and reliable fuel delivery. Because the pump installs inside the factory fuel tank, it retains the factory fuel lines, Water-In-Fuel sensor, and fuel heater while providing quiet operation compared to many frame-mounted lift pump systems.

Fleece's active fill bucket technology maintains fuel around the pumps and eliminates the need for a tank sump or draw straw. This design also helps prevent the quarter-tank fuel delivery issues commonly associated with some aftermarket high-flow fuel systems.

For custom fuel system configurations, the pump outlet and return ports are threaded to accept -8 O-ring fittings with 3/4"-16 threads. This allows aftermarket fuel lines or filtration components to be incorporated while retaining the benefits of the in-tank PowerFlo system.
