S&S Diesel Gen 2.1 Bypass Kit for Ford 6.7L Powerstroke

Introducing the S&S Diesel Gen 2.1 CP4 Disaster Prevention Kit with Return Filter for the 2011-2025 Ford 6.7L Powerstroke, a true game-changer for anybody looking to elevate the reliability of their ride. Recognized as the "Disaster Prevention Kit," this innovative solution addresses the well-known vulnerability of the CP4 high-pressure fuel pump. Known for its failure rates, a malfunctioning CP4 pump can unleash serious damage across your truck's high-pressure fuel system, including the injectors, rails, and lines. A fuel system failure like this can lead to costly repairs, often running into thousands of dollars for a complete system overhaul. Fortunately, the Gen 2.1 S&S Bypass Kit ingeniously reroutes the pump's bottom end flow directly back to the tank, all while filtering out any potential debris. This ensures the harmful particles are properly filtered out of before entering the rest of the fuel system.

High-Quality Construction & Design

Ease of installation the standout feature of this kit, equipped with OE-style quick connects and a fuel supply split-off positioned 25 inches from the CP4 pump for straightforward setup. The inclusion of a return filter assembly further improves protection by isolating CP4 debris, ensuring it never reaches your tank. A Gen2.1 billet filter head designed for standard spin-on fuel filters, coupled with a Donaldson P550943 fuel filter, guarantees unmatched filtration efficiency and convenience. Moreover, this kit is versatile, with a single part number catering to all models from 2011 onwards, and even boosts CP4 output beyond 3,000 RPM. If you want to ensure longevity and performance in your 6.7L Powerstroke, pick up the CP4 Disaster Prevention Kit w/ Return Filter today! Best of all, this system comes backed by a 2-Year limited warranty to help keep your investment protected.

Fits: 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 Ford F250/F350/F450/F550 Super Duty 6.7L Powerstroke

  • Only compatible with 6.7L Powerstroke diesel engines from 2011–2025; not for gas models.
  • Prevents debris spread in case of CP4 failure, but does not stop the pump from failing.
  • Professional installation is highly recommended for full system protection.
  • Filter (Donaldson P550943) requires periodic replacement to maintain debris isolation.

  • Kit does not interfere with CP4 output, even boosts it past 3,000 RPM.
  • Single SKU fits all supported years, Gen2.1 version simplifies ordering.
  • Comes with 2-Year limited warranty for added peace of mind.
  • CARB-compliant: EO# D-756-6 for emissions compliance where required.
