S&S Diesel Motorsport Ford 6.7L Fuel Leak Prevention Kit (2017-2026) – 6.7F17-LPK

Upgrade the two most common plastic failure points on your 2017–2026 Ford Super Duty 6.7L Power Stroke with the S&S Diesel Motorsport Fuel Leak Prevention Kit (LPK). This kit replaces the crack-prone OEM plastic engine-mounted fuel filter housing and the brittle plastic injector return fitting with durable billet aluminum components, while delivering filtration that meets or exceeds factory specifications.

Why You Need It

The factory plastic fuel filter housing is known to crack from heat and pressure, spraying diesel into the engine bay. The plastic injector return fitting is another frequent failure point. The S&S LPK eliminates both issues with precision-machined aluminum parts that are built to last. It works on completely stock fuel systems and is the perfect complement to an S&S Disaster Prevention Kit (DPK) or DCR Pump Conversion.

Key Features

• Billet aluminum engine-mounted fuel filter housing that directly replaces the crack-prone plastic OEM housing
• Donaldson spin-on fuel filter with OEM-spec filtration (4-micron absolute at 99% efficiency)
• Significantly higher dirt-holding capacity than the factory filter (S&S 23 grams vs. OEM 12 grams)
• Aluminum Fuel Leak Prevention Fitting with durable hose barb and easy-release quick-connect that replaces the brittle plastic OEM injector return fitting
• Direct-fit design for straightforward installation
• Made in the USA

Fitment

2017–2026 Ford F-250, F-350, F-450, F-550, F-650, and F-750 trucks with the 6.7L Power Stroke diesel.

Protect your fuel system from messy, expensive leaks and give it better filtration at the same time. The S&S Diesel Fuel Leak Prevention Kit is a smart, permanent upgrade for any 2017–2026 6.7L Power Stroke.
