The Bosch CP4 pump has been prone to pre-mature failure and can cause catastrophic fuel system contamination. After seeing the cost to replace a full fuel system, the S&S CP4 Bypass kit is good insurance.

The S&S Diesel Motorsport Gen2 6.7 Power Stroke CP4 Bypass Kit will feature all quick connect lines that eliminate the need for cutting the factory supply line, which is a debris introduction point, especially if the cut is not thoroughly deburred. It also eliminates the need to use a compression fitting, which is a potential leak point. The OE-style quick connect lines also eliminate any threaded joints that are further leak points and have the potential of generating debris during install.

The main task of both kits 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 kit accomplishes it. The Gen2 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 kit features a 2-micron filter in a clear firewall-mounted housing that prevents debris from reaching the tank, fuel lines, and supply pump. It can be visually inspected at a glance for debris, which will give notice to a failed 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.

One would think that major improvements would come at a major price increase. Having a clear understanding of common rail diesel fuel systems, and decades of OE engineering experience, enabled the engineers at S&S to make improvements without increasing production costs. Thanks to efficient design and use of material, the S&S Diesel Motorsport Gen2 6.7L Power Stroke CP4 Bypass Kit delivers much more value than the original, for an affordable price.
