A fuel lift pump is a must-have upgrade for any 2020-2025 GM 6.6L Duramax L5P that needs improved fuel flow, pressure, and overall performance. Lift pumps help ensure a steady supply of fuel to your engine, especially in high-demand situations like towing, hauling, or extreme off-roading. Upgrading to a performance lift pump not only boosts power but also protects your fuel system from cavitation and other fuel delivery issues. Along with these lift pumps, we also carry a selection of high-quality fuel filters that help keep your engine running smoothly. These filters effectively remove contaminants and debris, ensuring clean only fuel reaches your engine.
