S&S 2017-2026 6.7L Ford Power Stroke Fuel Leak Prevention Fitting (LPF)

At Full Send Diesel, we don’t just sell parts. We stand behind them. That’s why we fully back S&S Diesel Motorsport and proudly operate as an authorized premium dealer for their products. Their commitment to performance, reliability, and innovation aligns perfectly with our standards.

We don’t just support S&S as a brand. We run their products in our personal vehicles, our in-house builds, and every giveaway truck we put together. If it’s not good enough for our own trucks, it’s not good enough for our customers. S&S Diesel Motorsport has earned our full trust and support, both on and off the road.

S&S Diesel Motorsport

• All-metal replacement for the brittle plastic OEM injector return fitting, a known leak point on the 6.7L Power Stroke

• 6 pack available for shops that see these trucks every week
• Made in the USA

The factory injector return fitting is plastic, and heat cycles make it brittle until it cracks and leaks diesel. The S&S Fuel Leak Prevention Fitting (#6.7F17-LPF) replaces it with metal, permanently. Doing the fuel filter housing too? The S&S Fuel Leak Prevention Kit (LPK) handles both factory plastic failure points in one shot, also here at Full Send Diesel.
