Ford 6.7L Powerstroke Gen 2 Fuel Filter (2017-2019) — FD-4625 Cartridge Element The FD-4625 Fuel Filter Element is the exact-fit replacement for 2017-2019 Ford 6.7L Powerstroke Gen 2 engines. This drop-in cartridge replaces HC3Z-9N184-B and HC3Z-9N184-C with OEM-equivalent filtration performance. 2017+ Fuel System: What Changed For the second-generation 6.7L, Ford redesigned the fuel filter housing to a cartridge-style system. Unlike the 2011-2016 spin-on filter, the 2017+ uses a drop-in element inside a permanent canister. The quick-disconnect return line fitting (HC3Z-9A564-A) is a known failure point — we stock the replacement connector separately. Specifications Part Number FD-4625 OEM Cross-Reference HC3Z-9N184-B, HC3Z-9N184-C, Motorcraft FD-4625 Filter Type Cartridge (drop-in element) Filtration Rating 10 Micron Fitment 2017-2019 F-250, F-350, F-450, F-550 6.7L Powerstroke Service Interval Every 22,500 miles (drain water separator every oil change) Critical: Check Your Return Line Connector The fuel filter return line connector (HC3Z-9A564-A) on 2017+ models is a plastic quick-disconnect fitting known to crack and cause hard starting. If your truck cranks excessively before firing, replace this connector along with your filter. We stock it here. Installation Steps Locate filter canister on driver-side frame rail Drain water using the 6mm hex drain plug Unscrew the canister cap (36mm socket) Remove old cartridge element — note orientation Install new FD-4625 element, replace O-ring Reinstall cap — torque to 25 Nm Cycle ignition ON (not start) 6-8 times to prime Start engine, check for leaks FAQ Q: FD-4625 vs FD-4624 — what's the difference? A: FD-4624 was the original part number, superseded by FD-4625 with improved filtration media. FD-4625 is backward-compatible with all 2017-2019 applications. Q: Can I use the old spin-on filter (FD-4615) in my 2017+? A: No. The 2017+ fuel filter housing is completely different. You MUST use the FD-4625 cartridge element. Using the wrong filter type can damage the housing and cause leaks. Q: Why is my 2017+ 6.7L hard to start after sitting? A: The #1 cause is a cracked return line connector allowing air into the fuel system. Replace connector HC3Z-9A564-A (we stock it). Second most common cause: fuel draining back through a worn filter housing check valve. Q: How do I prime the fuel system after a filter change? A: Turn the key to ON (do NOT start) for 30 seconds. Turn OFF. Repeat 6-8 times. The in-tank pump will fill the filter housing and purge air. Starting without priming can cause extended cranking and possible CP4.2 damage.

Ford 6.7L Powerstroke Gen 2 Air Filter FA-1927 (2017-2019) The FA-1927 Engine Air Filter is the OEM-spec replacement for 2017-2019 Ford 6.7L Powerstroke Gen 2 engines. The aluminum-body Super Duty introduced a redesigned air intake system with a different filter element — the FA-1927 is NOT interchangeable with the earlier FA-1902. Specifications Part Number FA-1927 OEM Cross-Reference HC3Z-9601-A, Motorcraft FA-1927 Fitment 2017-2019 F-250, F-350, F-450, F-550 6.7L Powerstroke Service Interval Every 30,000 miles (check every oil change) FA-1902 vs FA-1927 — Know the Difference The 2017+ aluminum-body Super Duty uses a completely different air filter box from the 2011-2016 steel-body trucks. FA-1902 (2011-2016) and FA-1927 (2017-2019) are NOT interchangeable. The filter dimensions, seal profile, and mounting tabs are all different. FAQ Q: How do I know if my 2017+ truck has the original air filter? A: At 30,000+ miles, your factory filter is due for replacement regardless. A visual inspection: hold it up to a light — if you can't see light through the filter media, it's clogged. Q: Does a dirty air filter affect 6.7L fuel economy? A: Yes. A restricted air filter reduces turbo efficiency, causing the ECM to command more fuel for the same power output. At highway speeds, a clogged air filter can reduce MPG by 5-10% on a 6.7L Powerstroke.
