Genuine Motorcraft FD-4596 Fuel Filter | OEM Replacement for Ford 7.3L Powerstroke Diesel

Protect the legend under your hood. The 7.3L Powerstroke is world-renowned for its durability, but its HEUI injection system demands ultra-clean fuel to stay on the road. The Genuine Motorcraft FD-4596 is the factory-designed filter engineered to strip impurities and moisture before they can reach your injectors. Don't risk a "crank-no-start" or expensive injector damage by using a generic alternative—stick with the OEM standard that built the 7.3L's reputation.

🧠 WHY THIS MATTERS

At Valtrix Powertrain, we respect the legacy of the 7.3L. This engine utilizes high-pressure oil to fire the fuel injectors, and any contamination in the fuel side can cause internal wear that leads to poor spray patterns and power loss. The FD-4596 is thermally cycled to perform in extreme temperatures (from -40°F to 250°F) and features a 300-series stainless steel case for superior corrosion resistance against modern diesel additives and moisture.

❓ FAQ

Q: Does the FD-4596 come with the fuel bowl lid?

A: No, this is the filter element and the sealing gasket. You will reuse your existing factory fuel bowl lid.

Q: Can I use this on a 1994–1997 7.3L Powerstroke?

A: No. The 1999–2003 7.3L engines (Super Duty) use the FD-4596. The 1994–1997 "OBS" Ford trucks require a different filter style (FD-4595).

Q: How do I know if the filter is seated properly?

A: Place the filter into the bowl first, ensure it is centered, then screw the lid on. Always cycle the key to "On" 3 times to prime the bowl and check for leaks before starting.
