High-efficiency replacement fuel filter and water separator engineered to protect 6.7L Powerstroke engines in 2017–2025 Ford Super Duty trucks.

If you drive a Ford F-250, F-350, F-450 or F-550 with the 6.7L Powerstroke diesel from model years 2017 through 2025, this RARAYC fuel filter element kit gives you a direct-fit replacement for Motorcraft and Ford part numbers FD-4624/FD-4625 (HC3Z-9N184-B/C). The assembly combines a fuel filter and water separator to trap contaminants and separate water before fuel reaches the injection system, while included accessories speed up installation and reduce the need for extra parts.

How does this filter protect my Powerstroke engine?

The RARAYC element uses a high-grade filter media that captures the majority of solid contaminants and separates entrained water to reduce injector wear and clogging. It sits in the fuel path where it intercepts particles, rust, and moisture before fuel is delivered to high-pressure components.

• Removes up to 99.9% of particles 4 microns or larger
• Integrated water-separator design helps prevent water from reaching injectors
• Direct-fit for FD-4624/FD-4625 replacements—no modifications required

What comes in the RARAYC replacement kit and why it matters?

This kit includes the fuel filter/water separator plus the extra parts you need for a clean, reliable swap—so you avoid running back to the shop for a missing clip or gasket. A complete kit shortens downtime and ensures proper sealing and fuel return line retention.

• 1x fuel filter/water separator element
• 1x engine oil filter and 1x gasket for simultaneous maintenance
• 2x replacement return fuel line clips, installation guide, and safety gloves

How long will this filter last and when should I replace it?

Service life depends on driving conditions and fuel quality; typical replacement intervals align with manufacturer recommendations for fuel filter change on Powerstroke engines. Inspect during scheduled maintenance and replace earlier if you notice fuel system warning signs or contamination.

• Follow your vehicle manufacturer’s recommended maintenance intervals
• Replace sooner with poor fuel quality or heavy off-road use
• Kit includes gasket and clips to ensure correct reseal at each change
