Dependable Lift-Pump Support for Strong Fuel Delivery. The PowerFlo In-Tank Lift Fuel Pump for 2011–2016 6.6L Duramax Sierra 2500 HD models with 8-foot long box provides critical support to your 6.6L Duramax Sierra 2500 HD’s factory fuel system by helping maintain consistent fuel pressure under load. In turbo-diesel applications, especially when towing or under sustained high demand, a lift pump reduces the risk of fuel starvation at the injectors, leading to smoother throttle response, cooler EGTs (exhaust gas temperatures), and more consistent power delivery across the RPM range.

In-Tank Design for Quiet, Efficient Operation. Engineered to sit inside the factory fuel tank, the PowerFlo In-Tank Lift Fuel Pump integrates seamlessly with your Sierra’s existing setup, drawing fuel and pumping it toward the engine without the noise and heat of an external pump. This quiet, submerged configuration helps reduce the risk of cavitation and maintains a steady supply of fuel even under high demand, making it a smart choice for heavy towing, high-speed driving, or modified diesel engines that require extra fuel support.

Built for Durability in Tough Environments. The PowerFlo In-Tank Lift Fuel Pump is constructed from quality materials designed to withstand constant immersion in diesel fuel, heat cycles, and vibration common in pickup duties. Its rugged build resists premature wear and helps extend service life compared to weaker or undersized pumps, giving you confidence that your Duramax’s fuel system performs reliably mile after mile under real-world conditions.
