Fleece Performance FPE-SF-GM-0410 SureFlo Fuel Sending Unit Duramax - 2004.5-2010 2500/3500

The Fleece Performance FPE-SF-GM-0410 SureFlo Fuel Sending Unit is built for Duramax trucks running an externally mounted aftermarket fuel lift pump. It fits directly into the stock sending unit location and uses factory style quick disconnects to adapt your stock fuel lines at the tank. No cutting or drilling of the tank is required, and you don't need a draw straw or a tank sump.

SureFlo draws fuel from, and returns fuel to, the bucket assembly at the base of the unit. Your pump keeps pulling fuel instead of air, which helps prevent the cavitation that can occur with other pickup methods. The bucket also incorporates one way check valves so fuel can flow in easily, even at very low fuel levels.

This sending unit is a good alternative for trucks originally equipped without an in-tank pump that need to replace a malfunctioning level sender, or for owners who want to run their own custom fuel lines directly to the tank.

Key Features:

• OEM style fitment that requires no tank cutting or drilling
• 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 with O-ring

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