Fleece SureFlo® Performance Sending Unit (FPE-SF-GM-0104) for 2001-2004 Duramax LB7

The Fleece SureFlo Performance Sending Unit FPE-SF-GM-0104 helps solve fuel delivery problems when running an external lift pump on a 2001-2004 Duramax LB7 truck. Many aftermarket pumps mount external to the fuel tank. Because of this, installers often install a draw straw or drill the fuel tank to accommodate a sump. However, both options create drawbacks.

Problem

These setups commonly create the ¼ tank issue. When fuel levels drop, the pump may pull air into the fuel system. As a result, cavitation can occur and fuel delivery becomes inconsistent.

Fleece SureFlo Performance Sending Unit Solution

SureFlo performance sending units are designed to work with aftermarket lift pumps and fit directly into your stock sending unit location. The Fleece SureFlo Performance Sending Unit FPE-SF-GM-0104 also features factory style quick disconnects that adapt to the stock fuel lines at the tank. Because of this design, installation remains clean and requires no cutting or drilling of the tank.

SureFlo Bucket Fuel Delivery Design

SureFlo works by drawing fuel from, and returning fuel to, the bucket assembly at the base of the unit. Because of this design, the pump draws fuel instead of air. As a result, the system helps eliminate the common ¼ tank problem.

In addition, the SureFlo bucket incorporates one way check valves. These valves allow fuel to flow into the bucket more easily when fuel levels are low.

Additional SureFlo Sending Unit Benefits

Our SureFlo performance sending units are also a great alternative for trucks originally equipped without an in tank pump needing to repair a malfunctioning level sender. It also works well for trucks that want to run custom fuel lines directly to the tank.
