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. Our anodized billet aluminum fuel filter base has been designed to retain the proper fuel flow path across the PTC heating element to ensure 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 an OE quality fit and finish.

  • Donaldson 4 micron fuel filter and water separator (Donaldson P/N P553203)
  • Filter base with integral mounting
  • Distribution filter block / filter coupler
