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. Features: * New fuel level electronics and fuel float * Heavy-duty billet aluminum cap * Universal -8 AN ports for professionally plumbing a custom fuel setup * New O-ring or flange seal * Adaptation pigtail connector (where applicable)
