Product Description

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.

The S&S Diesel Motorsport Gen2.1 6.7L Power Stroke CP4 Disaster Prevention Kit features all quick connect lines that will 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.

Frequently Asked Questions

Will the S&S Diesel Gen2.1 CP4.2 Disaster Prevention Kit work with my 2011 6.7 Powerstroke, or do I need a different year?

Yes, this kit is specifically designed for 2011 and newer 6.7 Powerstroke engines, so it's compatible with your truck. The CP4-6.7F-BP-G2.1 model number confirms it's engineered for this exact application.

How difficult is the installation, and will I need special tools to install the Gen2.1 kit?

Installation is straightforward since the kit features OE-style quick connects, making it a bolt-on solution without requiring specialized tools. Most users report the installation can be completed in a few hours with basic hand tools.

What's the difference between the Gen2.1 and earlier versions of this CP4 prevention kit?

The Gen2.1 features a billet filter head that accepts standard spin-on fuel filters, making filter changes easier and more cost-effective than previous versions. This upgrade improves both durability and maintenance convenience.

How often do I need to replace the fuel filter on this disaster prevention kit?

Since it uses standard spin-on filters, replacement intervals depend on your driving conditions and fuel quality, typically every 10,000-15,000 miles. The Gen2.1 design makes filter changes quick and simple compared to proprietary systems.

Does this kit protect my entire fuel system, including the tank and injectors?

Yes, the Gen2.1 kit safeguards fuel injectors, rails, lines, and the tank by isolating CP4 debris before it can contaminate your system. The return filter specifically traps CP4 pump debris before fuel cycles back to the tank.
