Say Goodbye To Draw Straw Headaches For Good

If you're tired of dealing with air in the fuel system, cavitation, or cutting into your tank just to run an external lift pump, the Fleece SureFlo Performance Sending Unit is your clean and permanent fix.

It works seamlessly with most external lift pumps rated at 200 GPH or below, making it perfect for custom builds or fueling upgrades. SureFlo pulls fuel from the bucket assembly at the base, ensuring consistent supply even at low fuel levels and eliminating annoying quarter-tank issues. The included quick disconnect fittings make installation clean and easy, while the billet aluminum cap and new fuel level electronics add durability and reliability. Whether you're building a performance setup or replacing a faulty stock sender, SureFlo delivers the reliability and simplicity you’ve been looking for. It’s a cleaner, smarter way to fuel your truck.

Precision Built Fuel Pickup Solution With Clean Factory Fitment

The Fleece FPE-SF-GM-1116-SB SureFlo Performance Sending Unit is a purpose-built upgrade that addresses fuel supply issues common in externally pumped Duramax trucks. It replaces the factory sending unit and incorporates a high-flow design that draws and returns fuel directly from the bucket assembly inside the tank, reducing the chance of air ingestion and pump cavitation. The system uses built-in check valves to ensure consistent fuel pickup even at low levels and supports professional-grade plumbing with universal -8 AN ports. Installation is straightforward with no need to cut or modify the tank, and factory-style quick disconnects allow direct connection to stock fuel lines. It also includes new fuel level electronics and a float for reliable fuel gauge operation. Rated for use with lift pumps up to 200 GPH, this solution is ideal for performance applications that demand reliability without sacrificing simplicity. The billet aluminum cap and included O-ring seal complete a package designed to last under real-world conditions.
