2011-2025 Ford Powerstroke Gen2.1 CP4 Disaster Prevention Full Kit

Fits Ford F-250/F-350/F-450/F-550 Superduty w/ 6.7L Powerstroke -  2011-2026

The S&S Diesel Motorsport Gen2.1 Disaster Prevention Kit is the ultimate safeguard for your 6.7L Power Stroke. This "Full Kit" is designed for trucks currently running the factory setup. It works by supplying the CP4 pump case and the metering unit/plungers independently with clean, filtered fuel. In the event of a CP4 pump failure, this kit reroutes contaminated case fuel through a secondary filter before it can reach your injectors, rails, or fuel tank.

• Fuel supply is split 25 inches away from the CP4, preventing contaminated fuel from back-feeding into the clean supply line
• Billet filter head utilizes a standard, easy-to-find Donaldson spin-on filter
• Safeguards injectors, rails, lines, and the fuel tank
• OE-style quick connects eliminate potential leak points & debris from cutting factory lines
• Includes a Donaldson 9-micron (at 99% efficiency) spin-on filter
• Made in the USA

The main task of this kit is to supply the CP4 case and the metering unit/plungers independently with clean, filtered fuel, and to reroute case fuel back to the tank. There are two major improvements in how the Gen2.1 kit accomplishes this. The Gen2.1 fuel supply is split off into two separate lines 25 inches from the CP4, which will eliminate the chance of contaminated case fuel back-feeding into the clean fuel supply line. The original bypass kit splits off within an inch of the pump and is more susceptible to debris back-feeding if the CP4 failure produces enough debris to clog the fuel return system.

The other improvement is what happens to the debris when it exits the pump case. The Gen2.1 kit features a billet return filter head that accepts a readily available Donaldson Spin-On Fuel Filter (#P550943) that will prevent debris from reaching the tank, fuel lines, and supply pump. Previously, unfortunate victims of a CP4 failure, with the good fortune of having an original bypass kit installed, would still need to drop the tank and deal with all of the debris created by the failed CP4.
