Fleece Performance Under Bed Fuel Filter Assembly FPE-CUMM-UBFA-1924 | 2019–2024 Ram 2500/3500 6.7L Cummins

Tired of expensive OEM fuel filter replacements and fragile plastic housings that crack over time? The Fleece Performance Under Bed Fuel Filter Assembly (FPE-CUMM-UBFA-1924) is the premium solution for 2019–2024 Ram 2500 and 3500 trucks with the 6.7L Cummins. This direct-replacement upgrade swaps out the factory plastic filter housing for a durable, anodized billet aluminum base and converts your truck to the widely available, high-quality Donaldson P551329 spin-on fuel filter/water separator.

Why Ram Cummins Owners Choose This Upgrade

• Significant long-term savings — The Donaldson filter costs far less than the factory MOPAR filter and is easy to source anywhere.
• Superior durability — Replaces the brittle factory plastic assembly with a robust, corrosion-resistant anodized billet aluminum base.
• Excellent filtration — 13-micron Donaldson spin-on filter/water separator provides outstanding protection against contaminants.
