The Fleece Performance 04.5-10 GM Duramax SureFlo Performance Sending Unit is an innovative fuel system component designed to optimize fuel delivery for Duramax trucks. Built to work with externally mounted aftermarket lift pumps, it fits directly into the stock sending unit location, eliminating the need for tank modifications such as cutting or drilling. Key features include factory-style quick disconnects for seamless fuel line adaptation, a durable billet aluminum cap, and universal -8 AN ports for professional plumbing. The SureFlo unit draws fuel from and returns fuel to the bucket assembly at the base, ensuring consistent fuel flow and preventing cavitation issues associated with low fuel levels. It also incorporates check valves to facilitate fuel flow even at quarter tank levels, making it a reliable upgrade for high-performance applications.
Designed for 2004.5-2010 GM Duramax models, this sending unit is suitable for trucks originally without an in-tank pump or those needing to repair a malfunctioning fuel sender. It provides a straightforward, bolt-on upgrade that enhances fuel system reliability and performance, especially when running external lift pumps rated under 200 GPH. The kit includes a new fuel level electronics and float, along with a heavy-duty flange seal and fittings for professional installation. Ideal for custom fuel setups, towing, or high-performance driving, the SureFlo ensures consistent fuel delivery and simplifies installation without tank modifications.
