Fleece Performance 2020+ L5P Duramax Fuel Filter Upgrade Kit

The 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.  Our anodized billet aluminum fuel filter base retains the fuel flow through the OE sandwich style heating element that alternative designs lack.  The new filter base installs in the same location as the stock cartridge filter base and includes quick disconnect fittings for an OE quality fit and finish.

Kit includes: 

• Donaldson 3 micron fuel filter and water separator (Donaldson P/N P553203)
• Filter base with integral mounting
• Distribution filter block / filter coupler
• Quick disconnect fittings
• 1/8" NPT port for fuel pressure monitoring
