Fleece SureFlo Performance Fuel Tank Sending Unit FPE-SF-GM-0410

The Fleece FPE-SF-GM-0410 SureFlo Performance Sending Unit eliminates the need for drill holes in the fuel tank when installing a lift pump in your 2004.5-2010 GM 6.6L Duramax. If you are running an aftermarket lift pump that is mounted external of the fuel tank, you typically need to install a draw straw or drill your fuel tank to accommodate a sump. Each of these has some pretty significant drawbacks including the 1/4 tank issues that result in cavitation of the pump when you draw air into the fuel system.

The SureFlo performance sending units are designed to work with aftermarket lift pumps and fits directly into your stock sending unit location. It features factory style quick disconnects to adapt your stock 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 base of the unit. This ensures you are always drawing fuel into your pump and not drawing air into the fuel system as well as eliminates the dreaded 1/4 tank problems. The SureFlo bucket also incorporates one way check valves to allow fuel to easily flow in at lower levels. This sending unit is also a great alternative for trucks that need to repair a malfunctioning level sender or if you need run custom fuel lines directly to the tank.
