Fleece FPE-34789 PowerFlo In-tank Lift Pump – 2004.5-2007 LLY/LBZ

Fleece FPE-34789 PowerFlo In-tank Pump for 2004.5-2007 LLY/LBZ Duramax

The Fleece FPE-34789 PowerFlo In-tank Lift Pump is a high-performance OEM replacement from the diesel experts at Fleece Performance. Engineered to support up to 800 hp, this is the only in-tank lift pump with such capability, making it an ideal choice for diesel enthusiasts aiming to maximize engine performance. The PowerFlo lift pump enhances your engine’s efficiency by maintaining positive fuel pressure to the CP3, significantly reducing the strain on the injection pump.

Installation is straightforward, as the PowerFlo Lift Pump retains the factory fuel lines and can be installed in less than half the time compared to other high-flow lift pumps. Its dual gerotor design incorporates two OEM-quality pumps, which boosts both flow capacity and reliability, ensuring your engine receives the fuel it needs without interruption.

Seamless integration is another highlight of the PowerFlo. The active fill bucket design eliminates the necessity for tank sumps, draw straws, additional air filtration, and the common ¼ tank issues typically associated with higher-flow lift pumps. This feature allows for a cleaner, more efficient fuel system.

For those looking to customize their setup, the PowerFlo is aftermarket-ready. The pump’s outlet and return ports are threaded to accept a -8 O-ring fitting (3/4″-16 thread), making it compatible with custom fuel lines or aftermarket filters. This versatility ensures that the PowerFlo In-tank Lift Pump can meet the needs of both OEM systems and more specialized configurations, providing a robust solution that enhances both performance and reliability.
