L5P Fuel Filter Upgrade Kit (17-19 Short & Long Bed / 20-24 Long Bed) Fleece Performance

Spin-on filtration for the L5P

Fleece's patented kit changes the L5P Duramax from the factory cartridge filter to a spin-on canister. The canister holds more, lets you go longer between changes and opens up more filter options.

The anodized billet base keeps fuel flowing across the factory PTC heater element for cold-weather performance, mounts where the stock base was, and uses quick-disconnect fittings for an OE-style fit. A 1/8 in. NPT port is provided for a fuel pressure gauge.

Who it's for

Owners of 2017-2019 L5P Silverado/Sierra 2500/3500 trucks, and 2020-2024 crew cab long bed L5P trucks.
