Fleece Performance FPE-SF-GM-1116-SB SureFlo Fuel Sending Unit 2011-2016 GM Duramax Short Bed

The Fleece Performance SureFlo Performance Sending Unit is engineered to solve fuel delivery problems for Duramax owners running externally mounted aftermarket lift pumps. Designed for 2011-2016 Chevrolet Silverado and GMC Sierra 2500/3500 trucks with short bed configurations, this innovative sending unit eliminates the need for drilling your fuel tank or installing problematic draw straws that can cause cavitation and ½ tank fuel starvation issues.

The SureFlo system drops directly into your factory sending unit location and features OEM-style quick disconnect fittings that adapt seamlessly to your stock fuel lines at the tank. This provides the cleanest possible installation without any cutting or permanent modifications to your fuel tank. The unit's bucket assembly design draws fuel from and returns fuel to a reservoir at the base, ensuring consistent fuel delivery to your lift pump while preventing air from entering the fuel system.

Key Features:

• Direct OEM fitment—no tank cutting, drilling, or permanent modifications required
• Factory-style quick disconnect fittings for clean integration with stock fuel lines
• Integrated bucket assembly with one-way check valves for reliable fuel flow even at low tank levels
• New fuel level sending electronics and fuel float for accurate gauge readings
• Heavy-duty billet aluminum cap for durability and longevity
• Universal -8 AN ports for professional custom fuel system plumbing
• Includes new O-ring or flange seal for leak-free installation
• Includes -8 AN to 3/4-16 straight male fitting with O-ring

The SureFlo bucket's integrated check valves allow fuel to flow freely into the reservoir while preventing backflow, eliminating the common ½ tank fuel starvation problem that plagues many external pump setups. This sending unit is ideal for trucks that didn't come equipped with an in-tank pump, those needing fuel level sender repair, or enthusiasts building custom high-performance fuel systems. Compatible with aftermarket lift pumps rated up to 200 GPH.
