RARAYC Fuel Filter Element for 6.7L Powerstroke Super Duty (FD-4624/FD-4625) — Water Separator, 4μm

RARAYC Fuel Filter Element FD-4624/FD-4625 is a complete fuel filter and water separator kit designed to fit 2017–2025 Ford Super Duty 6.7L Powerstroke trucks, protecting the fuel system from particles and water.

This RARAYC kit replaces OE part numbers HC3Z-9N184-B / HC3Z-9N184-C and Motorcraft FD-4624 / FD-4625, giving you a ready-to-install solution that includes the fuel filter/water separator, an engine oil filter, gasket, replacement return fuel line clips, installation instructions, and safety gloves. Built from premium filter media, the element traps contaminants down to 4 microns and helps separate water before fuel reaches the injection system.

How does this filter protect my 6.7 Powerstroke on the road?

The RARAYC element combines mechanical filtration and water separation to keep fuel clean and dry, reducing the risk of injector clogging and poor combustion. Its media captures particles 4 microns or larger while the separator traps free water for easier draining or retention depending on design.

• Removes 99.9% of particles ≥4 microns.
• Integrated water-separating layer prevents water reaching injectors.
• Factory-style shape and sealing for reliable installation.

How long will this filter last and how should I maintain it?

Service intervals vary with driving conditions and fuel quality; many owners replace the fuel element at recommended Ford service intervals or sooner if water or heavy contamination is detected. The kit simplifies routine maintenance by supplying replacement clips and an oil filter so you can complete related tasks at the same time.

• Replace according to Ford’s maintenance schedule or when contamination appears.
• Inspect for water accumulation and drain when necessary (follow vehicle manual).
• Use included clips and gasket to ensure proper reseal after service.
