FD-4647 Fuel Filter Kit for 2017-2025 Ford 6.7L Powerstroke Super Duty 4 Micron, Anti-Gel Bypass Valve The iFJF FD-4647 fuel filter kit is a two-element diesel fuel service set for the 2017-2025 Ford F-250, F-350, F-450 and F-550 Super Duty trucks powered by the 6.7L Powerstroke V8. It replaces Motorcraft FD-4647 / FD-4624 / FD-4625-AA / FD-4641 and Ford OE PC3Z-9N184-C / HC3Z-9N184-B / LC3Z-9N184-A, filters particles down to 4 Micron, separates 98% of free water, and is rated for a 15,000-mile service interval. Every box contains the engine-mounted upper filter, the frame-mounted lower water separator, one pre-formed O-ring and one spare retaining clip. Key Takeaways 4 Micron Filtration: Multi-layer media captures particles down to 4 Micron before they reach the CP4.2 high-pressure fuel pump, protecting plungers and injectors from scoring. 98% Water Separation: The frame-mounted lower separator strips 98% of free water from diesel fuel, the leading cause of injector corrosion and hard cold starts. Anti-Gel Bypass Valve: An integrated bypass valve in the upper filter opens automatically when diesel gels on sub-freezing mornings, keeping fuel flowing instead of stalling the engine. 33% Glass-Fiber Reinforced Nylon 66 Housing: The upgraded injection-molded housing resists heat, vibration and cracking that brittle OEM-style housings develop over time. Complete Service Kit: Upper filter, lower water separator, O-ring and a spare retaining clip (HC3Z-9A317-A) are included, so the job finishes in one pass without a second trip for parts. Features & Benefits Feature Benefit (What It Means for You) 4 Micron multi-layer media Stops the abrasive particles that score CP4.2 pump plungers the failure mode that turns a $90 filter job into a $10,000 fuel system repair. 98% free-water separation Water is dropped into the drain bowl instead of travelling to the injectors, preventing corrosion, rough idle and hard winter starts. Built-in anti-gel bypass valve Gelled fuel bypasses the element instead of starving the engine, so a -10 F morning does not leave you stranded on the shoulder. 33% glass-fiber reinforced Nylon 66 upper housing Holds its shape under boost-level heat and heavy-tow vibration no hairline cracks, no fuel seepage onto a hot engine. Two-element kit with O-ring and spare clip Both service points are covered in one purchase; the extra clip saves the job when the original brittle clip snaps during removal. 15,000-mile service interval Matches Ford's severe-duty schedule (every third oil change), so one kit covers a full maintenance cycle.
