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

FOR LONG BED MODELS ONLY! 

If you are running an aftermarket lift pump that is mounted externally from the fuel tank (Such as Fass or Air Dog), typical install requires a draw straw or drilling your fuel tank to accommodate a sump.  Each of these has pros and cons, but if you aren't planning to run above a 220 GPH pump, and don't want to drill your fuel tank for a sump or deal with potential ¼ tank issues that result in cavitation of the pump when you draw air into the fuel system using a draw straw, then check out this slick option from Fleece that also doubles as a replacement fuel level sensor.

SureFlo performance sending units are designed to work with aftermarket lift pumps and fits directly into your stock sending unit 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.

Fleece SureFlo performance sending units are also 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.
