Sending Unit LB

The SureFlo performance sending unit from Fleece Performance is a drop-in replacement for the1999-2007 Ford 7.3/6.0L Powerstroke trucks needing to repair a malfunctioning fuel level sender or if you are looking to run your own custom fuel lines directly to the tank. SureFlo performance sending units are designed to work with aftermarket lift pumps and feature factory style quick connect fittings to adapt your stock fuel lines at the tank, giving you the cleanest installation available and requiring no cutting or drilling of the tank. Unlike the OE fuel senders that only use a pickup tube, the 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, eliminating the dreaded 1/4 tank problems. The SureFlo bucket also incorporates one way check valves that allow fuel to easily flow in at low levels.

If you are running an aftermarket pump that is mounted external of the fuel tank, you will need to install a draw straw or drill your fuel tank to accommodate a sump. Each of these has some significant drawbacks including the 1/4 tank issues that result in cavitation of the pump when you draw air into the fuel system. To resolve this issue there are Fleece Performance SureFlo performance sending units.

SureFlo units are designed to work with aftermarket lift pumps and fit directly into your stock sending unit location. Each one 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, ensuring you are always drawing fuel into your pump and not drawing air into the fuel system, as well as eliminating 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.

Fleece Performance SureFlo performance sending units are a great alternative for trucks originally equipped without an in-tank pump needing to repair a malfunctioning level sender or if you are simply looking to run your own custom fuel lines directly to the tank. Choose the SureFlo unit designed for your Cummins or Duramax fuel system.
