Product Details

For your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or the GMC Sierra equivalent, with the 6.6L LML Duramax engine, maintaining consistent fuel pressure is critical, especially if you've modified your truck. The Fleece Performance PowerFlo In-tank Lift Pump is designed to replace your stock fuel pump hanger assembly, providing a more robust and reliable fuel supply directly from the tank. This is particularly important for trucks that see heavy use or have had performance enhancements, as the factory system can sometimes struggle to keep up with increased fuel demands.

This unit is a well-built replacement for the stock fuel pump hanger, integrating a powerful lift pump right into the assembly. It's engineered to work with the factory fuel tank and lines, making installation more straightforward than a complete aftermarket tank setup. The pump itself is chosen for its ability to move fuel efficiently, helping to prevent fuel starvation under load and ensuring your engine receives the fuel it needs. This is a long bed only application, so be sure to check your truck's configuration before ordering.

When you're looking to support your LML Duramax, especially if you're planning on tuning or other upgrades, a reliable fuel supply is the foundation. This Fleece Performance lift pump is a solid option for ensuring your fuel system can handle the job. It's designed to be a direct replacement for the factory hanger, simplifying the installation process. Remember to consult the manufacturer's instructions for any specific details regarding installation and any other components that might be recommended for optimal performance.
