Short answer: The iFJF FD-4625 fuel filter kit is a two-element diesel fuel filter set for the 2017 2025 Ford 6.7L Powerstroke V8 in the F-250 through F-750 Super Duty. It replaces Motorcraft FD-4625 and FD-4624 and the Ford OE numbers HC3Z-9N184-B and HC3Z-9N184-C, separates 98% of water from diesel, and is rated for a 15,000-mile service interval. FD-4625 Fuel Filter Kit for 2017 2025 Ford 6.7L Powerstroke Engine & Frame Mounted Set The FD-4625 is the two-element fuel filter service set for the 2017-and-newer Ford 6.7L Powerstroke diesel. The 6.7L Powerstroke runs a two-stage fuel system, and this kit covers both stages: the frame-rail-mounted primary filter and water separator, and the engine-mounted secondary filter that protects the high-pressure CP4.2 injection pump. Both elements are direct replacements for Motorcraft FD-4625 and FD-4624 and for the Ford OE numbers HC3Z-9N184-B and HC3Z-9N184-C. Diesel fuel carries water and abrasive particulate straight from the pump to the injectors. On a common-rail engine the CP4.2 pump and its injectors are lubricated by the fuel itself, so contamination is not a filter problem it is a five-figure repair waiting to happen. This kit separates 98% of free water and traps fine particulate before it reaches the pump, keeping the fuel system clean and the injectors on spec. Key Takeaways Complete Two-Filter Service: Includes both the frame-rail primary filter/water separator and the engine-mounted secondary element, plus the housing gasket and a spare fuel return line retainer clip the full 6.7L Powerstroke fuel service in one box. Exact OEM Fit: Directly replaces Motorcraft FD-4625, FD-4624 and Ford OE HC3Z-9N184-B / HC3Z-9N184-C, plus the superseded FD-4625-AA, HC3Z-9N184-J, LC3Z-9N184-A and FD-4641 numbers. 98% Water Separation: Pulls free water out of the fuel stream before it reaches the CP4.2 high-pressure pump and the injectors. 15,000-Mile Service Interval: Rated for 15,000 miles or 12 months under normal duty, with a shorter severe-duty cycle for heavy towing and high-idle work. Broad Super Duty Coverage: Fits 2017 2025 F-250, F-350, F-450, F-550, F-600, F-650 and F-750 Super Duty trucks with the 6.7L Powerstroke V8 diesel. Features & Benefits Feature Benefit (What It Means for You) Two-Element Kit (Engine + Frame Mounted) Covers both stages of the 6.7L Powerstroke fuel system in a single purchase, so the water separator and the fine filter are replaced together the way Ford specifies the service. 98% Water Separation Free water is the number one cause of CP4.2 pump and injector failure. Separating it upstream keeps water out of the high-pressure rail and off your repair bill.
