S&S Diesel Motorsport Fuel Leak Prevention Kit 11-26 Ford 6.7L Powerstroke

Protect your 6.7L Powerstroke from fuel system failures before they become expensive repairs. The S&S Diesel Fuel Leak Prevention Kit eliminates factory plastic components that crack and leak over time, replacing them with precision-machined billet aluminum parts for improved reliability.

Every kit includes a billet aluminum engine-mounted fuel filter housing, billet aluminum injector return fitting, and a premium Donaldson spin-on engine fuel filter with 4-micron absolute filtration at 99% efficiency. The Donaldson filter doubles the dirt-holding capacity of the factory filter—capturing up to 23 grams of contaminants versus the OEM's 12 grams—protecting your high-pressure fuel system from harmful debris.

For complete fuel filtration system refresh, upgrade to the Fuel Leak Prevention Kit PLUS, which adds a premium Donaldson chassis-mounted fuel filter with OEM-spec 10-micron nominal filtration and over 40 grams of dirt-holding capacity.

Available for 2011-2016 and 2017-2026 Ford 6.7L Powerstroke applications. Proudly made in the USA. Works with stock fuel systems, S&S Disaster Prevention Kits, DCR Pump Conversions, and other fuel system upgrades. Whether you're replacing worn components or preventing future failures, this kit delivers the durability your Powerstroke deserves!
