SureFlo Performance Sending Unit for 2011-2016 LML Duramax Long Bed Fleece Performance

Feed an external lift pump properly

A frame-mounted aftermarket lift pump normally needs a draw straw or a sump drilled into the tank, and both can starve the pump and pull air below about a quarter tank. The SureFlo drops into the stock sending unit location instead, with factory-style quick disconnects for the stock lines and no cutting or drilling.

It draws from and returns to a bucket at its base, with one-way check valves that let fuel in at low levels, so the pump sees fuel instead of air.
