Fleece Performance SureFlo Performance Sending Unit for 2004-2010 GM Duramax 2500HD/3500HD - FPE-SF-GM-0410

Fits 2004-2010 Chevrolet Silverado and GMC Sierra 2500 HD, 3500, and 3500 HD trucks equipped with the Duramax diesel engine.

The Fleece Performance SureFlo Performance Sending Unit is engineered to eliminate the common "1/4 tank issue" that plagues modified fuel systems. When running an aftermarket external lift pump, traditional modifications like draw straws or sumps often lead to pump cavitation as fuel levels drop. The SureFlo unit replaces the factory sending unit and utilizes an internal bucket assembly to ensure your pump always draws from a reservoir of fuel, even during low-level conditions or high-slosh maneuvers.

This drop-in solution features integrated one-way check valves that allow fuel to flow into the bucket while preventing air from entering the system. It maintains OE-style quick disconnects for a clean installation that requires no cutting or drilling of the factory fuel tank. Note: The SureFlo is recommended for use with aftermarket lift pumps rated at 200 GPH or lower.
