iFJF part No.: FJ-FD4617. Ford 6.4L Powerstroke Fuel Filter FD-4617 Complete HPFP Protection The FD-4617 Fuel Filter is the correct OEM-spec replacement cartridge for 2008-2010 Ford 6.4L Powerstroke diesel engines. The 6.4L was Ford's first common-rail diesel with DPF, and its Siemens high-pressure fuel pump (HPFP) demands spotless fuel. This filter is your HPFP's first and best line of defense.

OEM-Spec Construction: Precision thread pattern and seal dimensions for leak-free fit. Direct replacement for 8C3Z-9N184-C and Motorcraft FD-4617. Complete Replacement Kit: Includes fresh O-ring seals for both the primary frame-mounted filter housing and the secondary engine-mounted housing. Heavy-Duty Durability: Reinforced filter media handles the elevated fuel temperatures generated during DPF regeneration cycles without degrading. Quantity Aware: Sold individually. Two FD-4617 filters required per service one for the frame-mounted primary housing and one for the engine-mounted secondary. Always replace both simultaneously.

Secondary is on the engine near the HPFP. Drain Water Separator: Use the drain valve on the primary housing to empty accumulated water before opening. Remove Old Cartridges: Unscrew housing caps, remove old filters, discard old O-rings. Install New O-Rings: Lubricate new O-rings with clean diesel fuel and seat them in the cap grooves. Insert New Filters: Place FD-4617 cartridges into housings, tighten caps to spec. Prime System: Cycle key to ON position 3-4 times (30 seconds each) to refill filter housings. Do NOT crank until the fuel system is primed. FAQ Q: How many FD-4617 filters does my 6.4L need? A: Two. Both the frame-mounted primary and engine-mounted secondary housings use the identical FD-4617 cartridge. Always replace both at the same service interval. Q: Why change 6.4L filters every 10K miles instead of 15K like the 6.7L? A: The 6.4L's DPF regeneration system injects fuel on the exhaust stroke to elevate exhaust temperatures, which circulates hotter fuel through the filter housings. Hotter fuel accelerates media degradation. The 10K interval is cheap insurance against a $3,000+ HPFP failure. Q: Are 6.4L and 6.0L fuel filters interchangeable? A: No. The 6.4L uses FD-4617 with specific thread patterns and seal dimensions. The 6.0L uses FD-4616. Using the wrong filter creates leaks and bypasses filtration entirely. Q: What happens if the HPFP fails? A: The Siemens HPFP ($3,000+ for the pump alone) sends metal
