Fleece Performance SureFlo Fuel Sending Unit Duramax

The Fleece Performance SureFlo Performance Sending Unit is a fuel tank sending unit (fuel level sender) for Duramax diesel trucks. It works as a direct replacement for a failed factory unit. It also suits setups that use an aftermarket lift pump mounted outside the tank. It installs in the stock sending unit location, so the tank doesn't need a draw straw, a drilled sump or any other modification.

SureFlo draws fuel from, and returns fuel to, a bucket assembly at the base of the unit. This keeps the pump pulling fuel instead of air. It also helps prevent the low-fuel (¼ tank) cavitation problems that affect externally mounted lift pumps. One-way check valves in the bucket let fuel flow in easily, even at low fuel levels.

Key Features:

• OEM-style fitment that requires no tank cutting or drilling
• New fuel level electronics and fuel float for accurate gauge readings
• Heavy-duty billet aluminum cap
• Universal -8 AN ports for a custom fuel plumbing setup
• New O-ring or flange seal
• Bucket design with one-way check valves to help keep fuel supplied to the pump

This is a sending unit only and does not include a pump. It is also a good choice for trucks that came without an in-tank pump and need a faulty level sender repaired, or for owners who want to run their own fuel lines directly to the tank.
