Fleece FPE-SF-GM-0104 SureFlo Performance Sending Unit

XDP has the Fleece FPE-SF-GM-0104 SureFlo Performance Sending Unit that will replace the broken unit in your 2001-2004 GM 6.6L Duramax LB7. If you are running an aftermarket pump that is mounted externally to the fuel tank, you will need to install a draw straw or drill into the fuel tank to accommodate a sump. Each of these has some substantial drawbacks including the 1/4 tank issues that result in cavitation of the pump when you draw air into the fuel system.

This SureFlo sending unit is engineered to work with aftermarket lift pumps and fits directly into the factory sending unit location. This unit features OEM-style quick disconnects to adapt the factory fuel lines at the tank, giving you the cleanest installation available, and requiring no cutting or drilling of the tank. SureFlo works by drawing fuel from, and returning fuel to, the bucket assembly at the top of the unit. This ensures you are always drawing fuel into the pump and not drawing air into the fuel system as well as eliminates the dreaded 1/4 tank issues. The SureFlo bucket also includes one-way check valves to allow fuel to easily flow in at lower levels. The 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, or if you are just looking to run your own custom fuel lines directly to the tank.
