PROBLEM: If you are running an aftermarket lift 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 pretty significant drawbacks including the ¼ tank issues that result in cavitation of the pump when you draw air into the fuel system. SOLUTION: SureFlo performance sending units are designed to work with aftermarket lift pumps and fit directly into your stock lift pump 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 ¼ tank problems. The SureFlo bucket also incorporates one way check valves to allow fuel to easily flow in at lower levels. IMPORTANT: SureFlo Sending Units for the 2017-2024 Ford Power Stroke DO NOT contain a fuel pump and are intended only for use in conjunction with an external frame mounted lift pump. For a direct replacement in-tank lift pump use our PowerFlo lift pump, part numbers FPE-PF-FMC-1724-SB and FPE-PF-FMC-1724-LB.
