The S&S Diesel Motorsport Fuel Leak Prevention Kit Plus (LPK+) is the complete fuel filtration upgrade for 2017-2026 Ford F-250, F-350, F-450, F-550, and F-650 trucks equipped with the 6.7L Power Stroke diesel engine. Designed to address one of the most common fuel system failures, the LPK+ replaces the factory plastic fuel filter housing with a precision-machined billet aluminum assembly while maintaining OEM-level filtration performance.
Unlike other solutions that solve one problem while creating another, the S&S LPK+ preserves the factory filtration specifications while dramatically improving durability and long-term reliability.
The LPK+ goes beyond simply preventing fuel leaks. This kit includes a Donaldson chassis-mounted replacement fuel filter, allowing you to refresh your entire fuel filtration system without purchasing Ford's complete two-filter service kit.
This convenient package provides everything needed to upgrade your fuel system while replacing the chassis-mounted filter during installation.
Rather than reusing the factory fuel filter cup, the LPK features a precision-machined billet aluminum two-post mounting system paired with a larger, high-efficiency fuel filter. This design maintains the factory filtration specification of 4-micron absolute filtration at 99% efficiency while nearly doubling the dirt-holding capacity of the original filter.
The included Donaldson chassis-mounted filter also meets OEM specifications with:
The result is superior contaminant protection, extended service life, and dependable fuel system performance without sacrificing filtration efficiency.
Replacing only the plastic filter housing leaves another common leak point untouched. That's why every S&S Fuel Leak Prevention Kit includes the billet aluminum Fuel Leak Prevention Fitting for the injector return, providing a complete solution to two of the most common fuel leak locations.
