If you're running an aftermarket pump mounted externally to the fuel tank, you typically need to install a draw straw or drill the tank to accommodate a sump. Both methods have significant drawbacks, such as the ¼ tank issue that causes pump cavitation when air enters the fuel system.

SureFlo performance sending units offer a solution designed to work seamlessly with aftermarket lift pumps, fitting directly into your stock sending unit location. These units feature factory-style quick disconnects that adapt to your stock fuel lines at the tank, providing the cleanest installation possible without the need for cutting or drilling. SureFlo draws fuel from and returns fuel to the bucket assembly at the base of the unit, ensuring continuous fuel flow into your pump and preventing air from entering the fuel system, effectively eliminating the ¼ tank problem. Additionally, the SureFlo bucket includes one-way check valves to facilitate easy fuel flow at lower levels.

SureFlo performance sending units are also an excellent alternative for trucks that were not originally equipped with an in-tank pump. They are ideal for repairing a malfunctioning level sender or for those looking to run custom fuel lines directly to the tank
