Gen2.1 CP4 Disaster Prevention Kit with Return Filter Assembly (2011+ 6.7L Power Stroke)

New and improved Gen2.1 CP4 Disaster Prevention Kit for 6.7L Power Stroke (2011+)

S&S Diesel Motorsport returns with a significantly refined Disaster Prevention Kit that protects your fuel system from CP4 failure debris — validated through extensive real-world testing. The Gen2.1 adds a billet return filter head and all OE-style quick connects for a cleaner install and superior debris management.

Key Features

• Improved Protection: Safeguards injectors, rails, lines, and tank from CP4 debris
• Real-World Proven: Thoroughly validated and proven to work in real-world testing
• Easy Install: All OE-style quick connects — no cutting, compression fittings, or extra threaded joints
• Clean Fuel Split: Fuel supply split-off occurs 25 inches from the CP4 to prevent back-feed contamination
• Return Filter System: Billet return filter head isolates debris before it reaches the tank
• Standard Spin-On Filter: Accepts readily available Donaldson P550943 (9-micron @ 99% efficiency)
• High-RPM Capability: Improves CP4 output past 3,000 RPM (see data below)
• Extended Range: Can extend drivable range in the event of a CP4 failure
• One Part Number Fits All: Single kit fits 2011+ 6.7L Power Stroke
• Compliance: CARB Compliant (EO# D-756-6)
• Built Proudly: Made in the USA

Why Gen2.1 Over the Original Kit?

• Cleaner Install: OE quick connects eliminate cutting the factory line and avoid compression fittings (common leak/debris sources)
• Smarter Fuel Routing: Dual supply lines split 25″ from the pump to reduce the chance of contaminated case fuel back-feeding
• Better Debris Control: Return fuel is filtered before reaching the tank, reducing or eliminating tank clean-out after a failure
