Sinister Diesel | 2011-2025 Ford Super Duty 6.7L Power Stroke Fuel Filter Conversion Kit

The Sinister Diesel Fuel Filter Conversion Kit is engineered to solve one of the biggest headaches for 6.7L Powerstroke owners — the cracking OEM plastic fuel filter housing. Once the stock unit fails, diesel fuel can spray across the top of the engine, creating a dangerous and costly problem.

Our conversion kit replaces that failure-prone design with a CNC-machined billet aluminum housing that’s built to handle high pressure, vibration, and heat without ever cracking or leaking. It installs in minutes using factory-style fittings, so no cutting or line modification is required.

Each kit includes a high-efficiency Baldwin fuel filter rated at 4 microns, providing superior protection against dirt, water, and particulates that can damage injectors and fuel pumps. The included billet fittings ensure leak-free performance, and the side port allows for easy expansion to dual-fuel systems or custom builds.

Reasons to Upgrade

• The factory plastic fuel filter housing on 6.7 Powerstrokes is one of the most failure-prone components under the hood. When it cracks at the top — a common issue — it sprays pressurized diesel across the engine bay, creating a serious mess and fire hazard.
• The Sinister Diesel Fuel Filter Conversion Kit eliminates that weak point with a billet aluminum housing that’s stronger, safer, and built to last the life of your truck.
• This system delivers 4-micron filtration for cleaner fuel, smoother engine performance, and longer injector life — all while simplifying service with affordable, easy-to-find replacement filters.
• Whether you tow heavy, daily drive, or push your truck at the track, this is one of the most important reliability upgrades you can make for your 6.7L Powerstroke.
