20C CHEVY/GM 2500/3500 DURAMAX L5P SB FUEL FILTER UPGRADE KIT

The Fleece Performance L5P fuel filter upgrade kit allows you to convert from a stock cartridge-style filter to a spin-on canister filter. This patented design increases filter capacity and extends change intervals, while also expanding your filter options.

Its anodized billet aluminum fuel filter base maintains the proper fuel flow path across the PTC heating element for maximum effectiveness in cold weather. The kit includes a Donaldson 4-micron fuel filter and water separator, a filter base with integral mounting, a distribution filter block, quick disconnect fittings, and a 1/8" NPT port for fuel pressure monitoring.
