Description
Order the Fleece FPE-FMC-UHFA-1123 Billet Under Hood Fuel Filter Assembly from XDP for your vehicle today. The plastic OE filters are prone to cracking and fuel leakage - eliminate the risk of a cracked filter with our billet aluminum cap assembly and billet aluminum quick disconnect fittings. Our drop-in replacement filter assembly locks directly into the stock filter location and utilizes a replaceable spin-on Donaldson filter that is easily serviceable. The kit includes an extra Donaldson fuel filter, further extending the time before you need to purchase an additional filter.
Understanding The 6.7L Powerstroke Fuel Filtration System
The fuel system for the 6.7L Powerstroke has a low-pressure (60-70 psi) fuel pump along with two independent fuel filter components. On the 2011-2016 trucks, the primary under-bed fuel filter is combined with the frame-mounted fuel pump assembly. In 2017, Ford moved the fuel pump to the fuel tank, with the under-bed filter mounted to the tank or frame rail, depending on bed length. Since 2011, all models have incorporated a secondary, under-hood filter that is mounted on the driver's side (left) valve cover.
Factory Filtration
Both the primary under-bed and secondary under-hood filters work together for water-coalescence and particle filtration, including filtration of the injector return fuel by the secondary filter. Ford Motorcraft markets these two filters as a pair, with a 5.1-micron rating and 98% efficiency. They do not publish the performance of each filter individually. When developing filtration kits for the 6.7L Powerstroke, Fleece separated the filters to independently verify the performance. Here are the findings:
2011-2016 Primary Under-Bed Fuel Filter - 20 Micron @ 89% Average Efficiency
2017-2026 Primary Under-Bed Fuel Filter - 20 Micron @ 96% Average Efficiency
2011-2025 Secondary Under-Hood Fuel Filter - 4 Micron @ 96% Average Efficiency / 10 micron @ 99% Average Efficiency
Advertised Combined System? 5.1 Microns at 98% efficiency.
Fleece Filtration
When developing a fuel filter kit for the 6.7L Powerstroke, Fleece worked with filter manufacturers to select filters that would perform on par with or better than the OEM units, and to provide a product that improves serviceability, availability, and durability. Beyond filtration capability, it is equally important to ensure proper flow rates and acceptable pressure drops are maintained in the filter selection. For consistency with OEM testing, performance data is reported at comparable efficiency and/or micron levels.
2011-2016 Fleece Performance Primary Under-Bed Fuel Filter - 20 Micron @ 94% Average Efficiency
2011-2026 Fleece Performance Secondary Under Hood Fuel Filter Assembly (With Donaldson Filter) - 4 Micron @ 95% Average Efficiency / 9 Micron @ 99% Average Efficiency

- Steel Adapter Fitting For The Filter

under hood filter
Greasy Nick (my garage) | May 29th, 2026
Easy to install. thought it would be a snugger fit like the OEM. But way better than the plastic. Next up is the under-body filter.
Under Hood Filter
Casey (North Dakota) | December 21st, 2025
Super easy to install. However, 4/5, as it is a MOFO to get off when changing the filter. I've even lubed the seal before applying, and it doesn't matter. I have to use a pair of channel locks every time I change the filter, and that's even installing hand-tight.
