The kit replaces Motorcraft FD-4647, FD-4624, FD-4625-AA and FD-4641, plus Ford OE PC3Z-9N184-C, HC3Z-9N184-B, HC3Z-9N184-C, HC3Z-9N184-J and LC3Z-9N184-A.\u003c\/p\u003e\n\u003ch4\u003eQ: How often should the FD-4647 fuel filter be replaced?\u003c\/h4\u003e\n\u003cp\u003eA: Replace the FD-4647 upper filter and lower water separator every 15,000 miles, which matches Ford's severe-duty schedule of every third oil change on the 6.7L Powerstroke. Trucks that tow heavy trailers, idle for long periods, or run in dusty or high-humidity conditions should shorten that interval to 10,000 miles and drain the water separator monthly.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between the FD-4647 and the FD-4625?\u003c\/h4\u003e\n\u003cp\u003eA: The FD-4647 and the FD-4625 both service the 2017-2025 Ford 6.7L Powerstroke, but the FD-4647 is the later upgraded design: it adds an anti-gel bypass valve inside the upper filter and uses a 33% glass-fiber reinforced Nylon 66 housing that resists the cracking and fuel leaks reported on earlier housings. The FD-4647 also cross-references the newer PC3Z-9N184-C and LC3Z-9N184-A part numbers.\u003c\/p\u003e\n\u003ch4\u003eQ: What is included in the FD-4647 kit?\u003c\/h4\u003e\n\u003cp\u003eA: Each FD-4647 kit contains one engine-mounted upper fuel filter, one frame-mounted lower fuel\/water separator, one pre-formed sealing O-ring and one spare retaining clip equivalent to HC3Z-9A317-A. Both filters and the seal are required for a complete service, so the kit covers the full job in a single purchase.\u003c\/p\u003e\n\u003ch4\u003eQ: Why does the FD-4647 have a bypass valve in the upper filter?\u003c\/h4\u003e\n\u003cp\u003eA: The bypass valve opens when diesel fuel gels in freezing weather and the element becomes restrictive. Instead of starving the CP4.2 high-pressure pump and stalling the engine, fuel routes around the element so the truck keeps running until the fuel warms up. This is a cold-climate protection feature that a standard filter element does not have.\u003c\/p\u003e\n\u003ch4\u003eQ: What part numbers does the FD-4647 replace?\u003c\/h4\u003e\n\u003cp\u003eA: The iFJF FD-4647 replaces Motorcraft FD-4647, FD-4624, FD-4625-AA and FD-4641, and Ford OE numbers PC3Z-9N184-C, HC3Z-9N184-B, HC3Z-9N184-C, HC3Z-9N184-J and LC3Z-9N184-A. Cross-reference the number stamped on your existing filter housing before ordering if your truck has had a filter base conversion.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I install the frame-mounted lower filter on a 6.7L Powerstroke?\u003c\/h4\u003e\n\u003cp\u003eA: Hold the old lower filter, slide it fully to the right, then pull it upward and out. Clean the housing, lubricate the new O-ring lightly with clean diesel and seat it evenly. Insert the new filter vertically on the right side and slide it fully to the left until it locks, then confirm the filter cannot wiggle or drop out. The engine-mounted upper filter threads onto the housing and should be tightened by hand plus a quarter turn only.\u003c\/p\u003e\n\n\u003cp style=\"font-size:0.92em;color:#666;margin-top:18px;\"\u003eEvery iFJF fuel filter is manufactured in a facility certified to ISO 9001:2015 and IATF 16949:2016 quality management standards.\u003c\/p\u003e","brand":"iFJF","offers":[{"title":"Default Title","offer_id":51973185405174,"sku":"FJ-4647-ZH","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3836\/3894\/files\/01_aae03687-8c41-4aca-8202-2a0ec0b30f99.jpg?v=1792395278","url":"https:\/\/ifjf.net\/products\/fd-4647-fuel-filter-kit-for-2017-2025-ford-6-7l-powerstroke","provider":"iFJF Direct","version":"1.0","type":"link"}
