Ford 6.7L Powerstroke (2017-2019)

Fuel Return Line Quick-Disconnect Connector for 2017-2020 Ford 6.7L Powerstroke If you smell diesel fuel near the passenger side of your 6.7L Powerstroke engine bay, there's a good chance the fuel return line connector is the culprit. This plastic quick-disconnect fitting lives in one of the hottest areas of the engine compartment and, over time, the locking tabs fatigue, the internal O-rings harden, and fuel begins to weep. What starts as a damp spot becomes a drip, and a drip becomes a low-pressure fuel leak that affects engine performance and creates a fire hazard. This direct-replacement connector restores a factory-tight seal on your fuel return circuit. Key Features OEM-Equivalent Quick-Disconnect: Engineered to the same dimensional specifications as Ford part HC3Z-9A564-A, ensuring a positive lock and leak-free seal on the fuel return line junction. Heat-Resistant Construction: Molded from high-temperature nylon formulated for continuous exposure to under-hood temperatures exceeding 250°F — it won't soften, deform, or lose locking tension like generic plastic fittings. Pre-Installed Viton O-Rings: The internal sealing O-rings are Viton (FKM) compound, not cheap Buna-N — Viton maintains elasticity and sealing force through diesel fuel exposure and extreme temperature cycling. Correct Locking Tab Profile: The locking tabs have the right spring tension and engagement depth to click firmly into place and stay locked — no false engagement, no unexpected disconnection from engine vibration. Wide Application Coverage: Fits all 2017-2020 Ford Super Duty trucks with the 6.7L Powerstroke, including F-250, F-350, F-450, and F-550 chassis cabs — one part number covers the entire lineup.

Wet or damp appearance on the connector body: Inspect the connector with a flashlight — look for fuel staining, dampness, or accumulated dirt that's been attracted by fuel residue. Loose or wobbly connection: The connector should be firmly seated with no side-to-side play. If you can wiggle it by hand, the locking tabs are worn beyond their service life. Visible cracking or stress marks on the connector body: Nylon that's been over-heat-cycled will show white stress marks (crazing) before it cracks. This is your early warning sign. Fuel drip on the ground near the passenger-side front wheel: Return line leaks often track down the frame rail and drip in this location, making them easy to misdiagnose as a fuel tank or filler neck issue. Installation Instructions Relieve fuel system pressure by removing the fuel pump fuse (fuse #40 in the under-hood fuse box) and running the engine until it stalls before disconnecting any fuel lines. Clean the area around the connector thoroughly with brake cleaner and compressed air — you don't want any dirt or debris entering the fuel system when the line is open. To release the old connector, squeeze both locking tabs simultaneously while pulling the connector straight off the fitting. Do NOT twist or pry — this damages the metal fuel line fitting. Inspect the metal fuel line fitting on the engine for corrosion, scoring, or burrs before installing the new connector. Clean with a Scotch-Brite pad if necessary. Push the new connector straight onto the fitting until you hear an audible "click" from both locking tabs. Give it a firm pull test to confirm positive engagement before restarting the engine. Frequently Asked Questions Q: Why did my original connector fail?A: The factory connector is exposed to extreme under-hood heat, especially on trucks used for heavy towing where exhaust gas temperatures and engine bay temps run high. Over years of thermal cycling, the nylon loses its elasticity and the locking tabs relax their grip. The internal O-rings also harden and lose their ability to maintain a seal. This is a wear item, not a design defect — it's simply reached the end of its service life. Q: Can I just replace the O-rings instead of the whole connector?A: While technically possible, it's not recommended. The connector body itself fatigues over time, and by the time the O-rings have failed, the locking tabs are usually compromised as well. Replacing the complete connector eliminates both failure points in one service. The part is inexpensive enough that the labor savings of doing it once justify the complete replacement. Q: Will this fit a 2011-2016 6.7L Powerstroke?A: No. The 2011-2016 trucks use a different fuel system layout with different connector configurations. This connector is designed for the 2017-2020 model years. Please verify your truck's production date — mid-cycle connector changes can occur. Q: Is this a high-pressure fuel line connector?A: No, this is a fuel return (low-pressure) line connector. It carries fuel returning from the injectors and the high-pressure pump back to the fuel tank at relatively low pressure. It should not be used on the high-pressure fuel feed lines between the HPFP and the fuel rails.

FD-4625 Fuel Filter Element for 2017-2019 Ford 6.7L Powerstroke — OEM-Grade Replacement The FD-4625 Fuel Filter Element is the direct OEM replacement for 2017, 2018, and 2019 Ford 6.7L Powerstroke diesel engines. This cartridge-style drop-in filter replaces Motorcraft FD-4625 (HC3Z-9N184-B & HC3Z-9N184-C) with equivalent 10-micron filtration performance at a fraction of dealer pricing. Precision-engineered for the second-generation 6.7L fuel system, this filter protects your high-pressure CP4.2 injection pump from water and particulate contamination. Second-Gen 6.7L Fuel System: What Changed in 2017 For the 2017 model year, Ford redesigned the 6.7L Powerstroke fuel filter housing from the earlier spin-on design (FD-4615) to a cartridge-style system. The FD-4625 drops into a permanent canister mounted on the driver-side frame rail, using a replaceable element instead of a disposable canister. This design improves serviceability and reduces waste — but it also means you cannot use 2011-2016 spin-on filters in a 2017+ truck. Make sure you're ordering the correct filter type. Key Features 10-Micron Filtration: Captures 99% of particles at 10 microns, matching OEM HC3Z-9N184-B specifications for reliable CP4.2 pump protection. Exact OEM Fit: Precision-molded end caps and O-ring grooves ensure a leak-free seal inside the factory filter housing — no modifications needed. Complete Kit: Includes filter element + replacement housing O-ring. Everything you need for a standard service. IATF 16949 Certified: Manufactured under automotive quality management standards, delivering OEM-equivalent reliability at aftermarket pricing. Extended Service Life: Rated for 22,500-mile service intervals under normal driving conditions (15,000 miles for severe duty/towing).

Technical Specifications Part Number FD-4625 OEM Cross-Reference HC3Z-9N184-B, HC3Z-9N184-C, Motorcraft FD-4625 Superseded From FD-4624 (improved media in FD-4625 — backward compatible) Filter Type Cartridge Element (drop-in) Filtration Rating 10 Micron Nominal Service Interval 22,500 miles (every 3rd oil change) — 15,000 miles severe duty Installation Location Driver-side frame rail, under driver door area Housing Cap Torque 25 Nm (18 ft-lbs) ⚠️ Before You Start: The fuel filter return line connector (HC3Z-9A564-A) on 2017+ 6.7L Powerstroke models is a known failure point. If your truck cranks excessively before firing, replace this $15 connector alongside your filter — we stock it separately. Installation Steps Locate fuel filter housing on driver-side frame rail, just behind the front wheel Drain water from the separator using the 6mm hex drain plug — catch fuel in a container Unscrew the housing cap using a 36mm socket — do NOT use a strap wrench (may crack the cap) Remove old cartridge element — note the orientation before pulling it out Install the new FD-4625 element — it only seats correctly in one direction Replace the housing O-ring with the new one included in this kit Reinstall cap and torque to 25 Nm (18 ft-lbs) Cycle ignition to ON (do NOT start) for 30 seconds, then OFF — repeat 6-8 times to prime the system Start engine and inspect for leaks at the cap and drain plug Why Choose iFJF FD-4625 Over OEM? Same 10-Micron Protection — No compromise on filtration. Your CP4.2 pump is too expensive to gamble on cheap filters. 50-60% Less Than Dealer Pricing — Motorcraft FD-4625 runs $60-80 at Ford dealers.

No 2-week AliExpress wait times. 12-Month Warranty — Every iFJF filter is backed by our hassle-free replacement guarantee. Frequently Asked Questions Q: FD-4625 vs. FD-4624 — what's the difference and which one do I need? A: FD-4624 was the original part number when the second-gen 6.7L launched in 2017. Motorcraft superseded it with FD-4625, which uses improved filtration media for better water separation and longer service life. FD-4625 is 100% backward-compatible with all 2017-2019 applications. If you're seeing FD-4624 referenced, the FD-4625 in this listing is the correct current replacement. Q: Will this fit my 2017/2018/2019 F-250 or F-350? A: Yes — the FD-4625 fits all 2017, 2018, and 2019 Ford F-250, F-350, F-450, and F-550 Super Duty trucks with the 6.7L Powerstroke V8 diesel engine. It does NOT fit 2011-2016 models (they use spin-on FD-4615) or 2020+ models (they use FD-4631). Always confirm your model year before ordering. Q: How often should I replace the fuel filter on my 6.7L Powerstroke? A: Ford recommends every 22,500 miles (typically every 3rd oil change at 7,500-mile intervals). If you tow heavy, idle frequently, run biodiesel blends above B5, or operate in dusty conditions, replace every 15,000 miles. Always drain the water separator at every oil change regardless of mileage. Q: Why is my 2017+ 6.7L hard to start after sitting overnight? A: The #1 cause is a cracked fuel return line connector (HC3Z-9A564-A) allowing air into the system and fuel to drain back to the tank. Replace this $15 plastic connector before replacing injectors or high-pressure pumps. Second most common cause: a worn housing cap O-ring letting air in — always replace the O-ring with every filter change. Q: Can I reuse the old O-ring if it looks fine? A: No. The housing cap O-ring is a one-time-use seal. Even if it looks fine, heat cycling causes micro-compression that prevents a proper seal on reinstallation. A leaking O-ring can cause extended cranking, rough idle, and eventual CP4.2 damage from air in the fuel system. Every FD-4625 kit includes a new O-ring — use it. Q: What tools do I need to change this filter? A: A 36mm socket (or 1-7/16" SAE) for the housing cap, a 6mm hex key (Allen wrench) for the drain plug, a drain pan to catch fuel, and shop rags. No special tools required. Most DIYers complete the job in 20-30 minutes.

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.
