Fuel Filter Conversion Kit for Ford F250 F350 F450 F550 6.7L Powerstroke
Stop paying premium prices for failing plastic filter housings on your 6.7L Powerstroke. This fuel filter conversion kit replaces the fragile upper factory plastic assembly with a robust metal housing designed specifically for 2011–2022 Ford F250, F350, F450, and F550 Super Duty trucks. By switching to widely available metal aftermarket filters like the Baldwin BF7967, WIX 33386, or standard 33393, you cut maintenance costs while improving fuel flow across the board. The unit also integrates seamlessly into modified systems, acting as a clean fuel distribution block that replaces cluttered tee fittings and strengthens the original injector return line without leaks or cracks.
Benefits & Tips
Upgrading to this metal filter setup keeps your truck running reliably under heavy loads or aggressive tunes. Here is how to get the most out of the installation:
- Use during scheduled routine service to keep filter swapping quick and cheap.
- Pair the upgraded flow capacity with high-performance tune files for consistent pressure at the injectors.
- Inspect the sealing O-rings before reassembly to prevent vacuum leaks that can cause hard starting.
