Improve your 2017-2024 L5P Duramax's fuel filtration with the Fleece Performance Fuel Filter Base Kit. This kit is designed to enhance fuel filtration efficiency and protect your engine against contaminants, ensuring optimal performance.

The patented Fleece Performance L5P fuel filter upgrade kit allows you to seamlessly change over from the stock cartridge-style filter to a spin-on canister-style filter. The canister filter provides for increased filter capacity and longer change intervals as well as expands your filter options. The anodized billet aluminum fuel filter base has been designed to maintain the proper fuel flow path across the PTC heating element, ensuring maximum effectiveness in cold weather. The new filter base installs in the same location as the stock cartridge filter base and includes quick-disconnect fittings for OE-quality fit and finish.
