S&S Diesel Motorsport, the creator of the original Disaster Prevention Kit for the 6.7 Power Stroke, is at it again with a much-improved second-generation kit. Since its debut in 2016, the original S&S 6.7L Power Stroke CP4 Bypass Kit (Disaster Prevention Kit) has safeguarded thousands of injectors from CP4 debris. Being a company founded by fuel system engineers, S&S Diesel Motorsport has the ability, and responsibility, to offer the best solutions to fuel system problems. While the original bypass kit offers really good protection from a CP4 failure, the last four years have given the S&S engineers plenty of time to discover and eliminate potential problems. To top it off, the CP4-6.7F-BP-G2.1 are now Carb Compliant!

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.

If you've already got a disaster kit but you want to upgrade your kit to the newest setup then we offer upgraded return filter assemblies or upgraded filter heads to make sure that you're not left behind if you've already got S&S's setup.
