Fleece Performance FPE-L5P-FFBA-20 L5P Fuel Filter Upgrade Kit 2020-2024 Duramax

The Fleece Performance L5P Fuel Filter Upgrade Kit enables you to convert from the factory cartridge-style filter to a superior spin-on canister filter system. This upgrade provides increased filtration capacity, extended service intervals, and a wider range of replacement filter options for your 2020-2024 Silverado/Sierra 2500/3500 with the L5P Duramax engine.

Engineered specifically for short bed trucks (2020-2024) and 2024 standard cab long bed configurations, this kit features a precision-machined billet aluminum filter base with black anodized finish. The design maintains proper fuel flow across the PTC heating element, ensuring reliable cold-weather performance and preventing fuel gelling in harsh conditions.

Installation is straightforward, with the new filter base mounting in the original location using included quick-disconnect fittings for a factory-quality fit. The integrated 1/8-inch NPT port allows for easy fuel pressure monitoring.

Complete Kit Includes:

• Donaldson 3-micron fuel filter and water separator (P/N P553203)
• Billet aluminum filter base with integral mounting hardware
• Distribution filter block and filter coupler
• Quick-disconnect fittings for factory-style installation
• 1/8-inch NPT port for fuel pressure gauge installation

This conversion kit provides superior filtration protection for your L5P Duramax fuel system while simplifying maintenance with readily available spin-on filter replacements.
