RARAYC Fuel Filter Element FD-4624/FD-4625 for 6.7L Powerstroke (2017–2025) — Direct-Fit Water Separator, OE Replacement

RARAYC Fuel Filter Element FD-4624/FD-4625 is a direct-fit fuel filter and water separator kit engineered to protect 6.7L Powerstroke engines in 2017–2025 Ford Super Duty trucks by capturing contaminants and separating water before fuel reaches the injectors.

This RARAYC kit replaces OE part numbers HC3Z-9N184-B / HC3Z-9N184-C and Motorcraft FD-4624/FD-4625, delivering filtration performance designed for F-250, F-350, F-450 and F-550 models powered by the 6.7L Powerstroke. The package includes a fuel filter/water separator, engine oil filter, gasket, two replacement return fuel line clips, an installation guide and a pair of safety gloves—so you have the core parts needed for a routine service. Built from high-efficiency media, the element captures fine particles and helps keep the fuel system cleaner between scheduled maintenance intervals.

How does this filter protect my Powerstroke on the road?

The RARAYC element traps contaminants down to approximately 4 microns and separates free water, which prevents abrasive particles and moisture from reaching high-pressure fuel components. Cleaner fuel reduces wear on the pump and injectors and helps maintain consistent engine performance under load.

• Removes 99.9% of particles 4 microns or larger
• Integrated water-separating design to collect free water
• OEM-equivalent fit for factory mounting locations
• Includes replacement clips and gasket to ensure a secure install

Will this fit my Ford Super Duty from 2017 to 2025?

Yes—this RARAYC filter is made to be compatible with 2017–2025 Ford F-250, F-350, F-450 and F-550 trucks that use the 6.7L Powerstroke engine and match the listed OE part numbers. Always cross-check the vehicle’s part number or VIN to confirm compatibility before installation.
