Product Overview
The factory fuel filter housing on the 6.7L Powerstroke is a known weak point. Made from plastic, it’s prone to cracking at the cap, often spraying pressurized diesel fuel across the engine bay. When it fails, it creates a mess at best—and a serious safety concern at worst.
The Sinister Diesel Fuel Filter Conversion Kit permanently solves this issue by replacing the OEM plastic housing with a CNC-machined billet aluminum unit designed to handle heat, pressure, and vibration without cracking or leaking. It installs directly in place of the factory housing in under 10 minutes, with no cutting or line modifications required.
This kit is engineered to work with both 2-line and 3-line 6.7L Powerstroke fuel systems. Every kit includes the third port along with a threaded plug, ensuring proper sealing and compatibility regardless of your truck’s factory fuel line configuration.
Fuel filtration remains consistent with OEM requirements by using a Baldwin 4-micron filter that matches factory filtration specs, providing proper injector and pump protection without altering fuel flow or pressure characteristics.
Recommended Filter Service Interval
Fuel filter maintenance should follow OEM service recommendations. As a general guideline, most trucks will require filter replacement approximately every 15,000 miles or once per year, depending on driving conditions and fuel quality.

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.
