S&S Diesel 6.7F11-LPK – Ford 6.7L Fuel Leak Prevention Kit (2011-2016)

Protect your 6.7L Power Stroke from one of the most common (and expensive) failure points with the S&S Diesel Fuel Leak Prevention Kit. The 6.7F11-LPK replaces the failure-prone plastic OEM engine-mounted fuel filter housing and the brittle plastic injector return fitting with durable billet aluminum components—stopping cracks and leaks before they start.

What’s Included

• Billet aluminum engine-mounted fuel filter housing (direct replacement for the crack-prone plastic OEM unit)
• High-capacity Donaldson spin-on fuel filter – 4-micron absolute filtration at 99% efficiency – Significantly higher dirt-holding capacity (23 grams vs. OEM 12 grams)
• Aluminum Fuel Leak Prevention Fitting for the injector return line (easy-release quick-connect hose barb)

Why It Matters

Plastic OEM filter housings and return fittings are known to crack from heat, vibration, and age, leading to fuel leaks, hard starts, low pressure, and potential engine damage. The S&S billet aluminum housing and fitting eliminate these weak points while delivering superior filtration.

Perfect For

• 2011–2016 Ford F-250 to F-550 trucks with the 6.7L Power Stroke
• Stock fuel systems, trucks already running the S&S Disaster Prevention Kit (DPK), or vehicles with the DCR pump conversion
• Owners who want a clean, permanent upgrade that improves reliability and filtration in one install

Made in the USA.

Upgrade your 6.7L fuel system with the proven protection of the S&S Fuel Leak Prevention Kit and keep fuel where it belongs—inside the system.
