Fleece Performance SureFlo® Performance Sending Unit – 2003-2004 5.9L Cummins Part # FPE-SF-CUMM-0304

Eliminate the dreaded ¼-tank problem and run your aftermarket lift pump the right way—without cutting or drilling your fuel tank.

The Fleece SureFlo Performance Sending Unit is the cleanest, most reliable solution for 2003–2004 Dodge Ram 5.9L Cummins trucks running an external lift pump (FASS, AirDog, etc.) up to 220 GPH. It drops directly into the factory sending unit location and uses the stock tank opening—no tank modification required.

How it works

SureFlo draws fuel from (and returns fuel to) a specialized bucket assembly at the bottom of the unit. One-way check valves keep the bucket full even at low fuel levels, so your lift pump is always pulling liquid fuel instead of air. This completely eliminates the starvation and cavitation issues common with draw straws when the tank drops below ¼ full.
