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.
Product Description
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.

Q&A
Q: Why should I upgrade to the Sinister Diesel Fuel Filter Conversion Kit?
A: The factory plastic fuel filter housing on 6.7L Powerstroke engines is notorious for cracking at the top — often without warning. When that happens, diesel fuel sprays throughout your engine bay, creating a mess, a fire hazard, and an expensive repair. Our billet aluminum filter base eliminates that weak point entirely, giving you a permanent fix and peace of mind.
Q: What filter does this kit use?
A: The kit uses the Baldwin BF7967 spin-on fuel filter — a heavy-duty, industry-proven design with a 4-micron nominal and 15-micron absolute rating. It delivers the same filtration performance as the OEM setup while providing easier, cleaner service intervals.
Q: How does this compare to the factory Ford filter system?
A: Ford’s plastic upper filter housing has been a recurring failure point for years, while the Sinister Diesel billet aluminum base is CNC-machined from solid 6061 aluminum for maximum strength and durability. You’ll never have to worry about cracked housings or stripped threads again.
Q: Is installation difficult?
A: Not at all. Most customers complete the install in under 30 minutes using basic hand tools. The kit is designed to bolt directly into place — no modifications, cutting, or special fittings required.
Q: Will this affect fuel flow or system performance?
A: No — the BF7967 filter provides equivalent filtration and flow to the factory element. Your truck will maintain factory fuel pressure and flow characteristics, while offering better serviceability and reliability.
Q: How often should the filter be changed?
A: We recommend replacing the Baldwin BF7967 at the same interval as your factory fuel filter — typically every 15,000 miles, or sooner if you operate in dusty or off-road environments.
