Fleece Fuel Filter Upgrade Kit (2020-Current GM 6.6L Duramax)


The Fleece FPE-L5P-FFBA-20 Fuel Filter Upgrade Kit upgrades the stock cartridge style filter to a spin-on canister style filter in your 2020 GM 6.6L Duramax L5P. Canister style filters have longer service life due to an increased filter capacity and give you more filter options to choose from. The included anodized billet aluminum fuel filter base retains the factory sandwich style heating element for cold weather. This filter base mounts in the identical location as the factory cartridge filter base and comes with quick disconnect fittings for OE quality fit and finish.   



  • Quick Disconnect Fittings 
  • Filter Base With Integrated Mounting 
  • Distribution Filter Block & Filter Coupler 
  • Donaldson 3 Micron Fuel Filter & Water Separator 


Replacement filter Donaldson Part Number P553203.

Fuel heater not included. This kit reuses factory fuel heater.
