Fleece SureFlo Performance Sending Unit (Long Bed) for 2011-2016 Chevy/GMC LML Duramax

Long bed LML with an external lift pump? Don't drill the tank. Swap the sender.

SureFlo works with externally mounted aftermarket lift pumps and fits right in the factory sending unit location. A bucket at the base keeps your pump fed with fuel, not air, so the quarter tank problem is gone. It's also a clean way to fix a bad level sender or run your own lines to the tank.

Features

• Drops into the stock sending unit location with no tank cutting or drilling
• Factory style quick disconnects adapt your stock fuel lines at the tank for a clean install
• Draws fuel from and returns fuel to the bucket assembly at the base of the unit, so your pump pulls fuel instead of air and the 1/4 tank problem goes away
• One way check valves in the bucket let fuel flow in easily, even at the lowest fuel levels
• New fuel level electronics and fuel float
• Heavy duty billet aluminum cap
• Universal -8 AN ports for professional plumbing of a custom fuel setup
• New O-ring or flange seal
• 8 to 3/4'-16 straight male fitting w/ O-ring

Note: SureFlo is not recommended for use with aftermarket lift pumps that exceed a 200 GPH rating. Long bed version.

Tuning with PPEI

PPEI recommends a properly fed fuel system on any LML with PPEI engine tuning, and we run Fleece fuel parts on our own trucks. SureFlo keeps your lift pump fed, so the tune makes the same power and throttle response at a low tank as it does full.
