Genuine Motorcraft FD-4625 Fuel Filter Kit | OEM Replacement for 2017–2022 Ford 6.7L Powerstroke Diesel

Stop the "CP4 death" before it starts. The 2017+ Ford 6.7L Powerstroke is a high-output beast, but it is notorious for fuel system sensitivity. The Genuine Motorcraft FD-4625 is the only factory-approved dual-filter system engineered to handle the increased flow rates of the Gen-2 and Gen-3 Powerstroke. Don't gamble with "white-box" filters that allow water into your high-pressure rail—protect your $10,000 fuel system with OEM precision.

🧠 WHY THIS MATTERS

At Valtrix Powertrain, we focus on preventative maintenance for high-value diesel engines. The FD-4625 isn't just a filter change; it’s a mission-critical service. This kit utilizes Ford’s latest Aqua-Bloc media to separate 99% of water while maintaining a 4-micron absolute filtration rating. For 2017+ trucks, the fuel pump operates at higher pressures than previous generations, making the structural integrity of your filter elements more important than ever.

❓ FAQ

Q: Is the FD-4625 the same as the FD-4615?

A: No. The FD-4615 is for 2011–2016 trucks. The FD-4625 is for the updated 2017–2022 chassis. They are NOT interchangeable.

Q: Does this kit fit the new 2023–2024 models?

A: Most 2023+ models transitioned to a different filter housing (FD-2141). Always verify with your VIN before ordering for a 2023+ truck.

Q: Do I need to "purge" air after installation?

A: Yes. Turn the key to the 'ON' position (don't crank) for 30 seconds. Repeat this 6 times. You will hear the lift pump humming as it pushes air out of the system—this prevents a "dry start" on your CP4 pump.
