S&S Gen 2.1 (MY2011+) 6.7L Power Stroke CP4 Bypass Kit with Return Filter Assembly

The new Gen 2.1 S&S 6.7L Ford Power Stroke CP4.2 Bypass Kit, or commonly called the “Disaster Prevention Kit,” does exactly what the nickname implies, it prevents the disastrous consequences of an inevitable CP4 pump failure from destroying the rest of a very expensive high-pressure fuel system.

CP4 high pressure pumps are the Achilles heel of the 6.7L Ford Power Stroke engine due to high failure rates, which commonly take out the entire very costly high-pressure system with it (injectors, rails, lines). When the CP4 fails, it sends debris into the rest of the system and requires a several thousand-dollar replacement of injectors, rails, lines, etc. The S&S Bypass Kit reroutes the pump bottom end flow back to the tank and filters and prevents the CP4 debris from getting to the rest of the high-pressure system.

This is a 100% USA-made kit requires no additional tuning or modifications after installation and comes with a manufacturers two-year warranty.

This new Gen 2.1 kit features: 

• All OE-style quick connects (easy install)
• Fuel supply split-off 25 inches away from the CP4 pump
• Return filter isolates CP4 debris before it goes on to the tank
• Gen2.1 billet filter head accepts standard spin-on fuel filters
• Comes with Donaldson P550943 fuel filter (9-micron at 99% efficiency)
• One part number fits all years (2011+)
• Improves CP4 output past 3,000 RPM (see attached graph)
• Made in the USA
