S&S Diesel Motorsport 6.7 Powerstroke Disaster Prevention Kit Fits: 6.7 Powerstroke 2011-2025

S&S Diesel Gen2.1 CP4 Disaster Prevention Bypass Kit (CP4-6.7F-BP-G2.1) – 6.7 Powerstroke

Protect your 2011–2025 Ford 6.7L Powerstroke fuel system from one of the most expensive failures in the diesel world. The factory CP4 high-pressure fuel pump is known for sudden, catastrophic failures that send metal debris through injectors, rails, fuel lines, and even back into the tank—often resulting in repair bills of $8,000–$12,000+.

The S&S Diesel Motorsport Gen2.1 CP4 Disaster Prevention Kit (part # CP4-6.7F-BP-G2.1) is the upgraded, second-generation solution from the company that pioneered this protection concept in 2016. It has safeguarded thousands of trucks and continues to set the standard.

How the Gen2.1 Kit Works

This bypass kit supplies clean, filtered fuel independently to the CP4 pump case and metering unit/plungers. In the event of a CP4 failure, contaminated case fuel is rerouted through a high-efficiency return filter before it can reach your injectors, rails, lines, lift pump, or fuel tank.

Major Gen2.1 improvements over the original kit include:

• Fuel supply split-off point moved 25 inches away from the CP4 (greatly reduces risk of debris back-feeding into the clean supply line).
• All OE-style quick-connect fittings — no cutting the factory supply line, no compression fittings, and fewer potential leak or debris-introduction points during installation.
• CNC-machined billet aluminum return filter head that uses a standard, readily available Donaldson P550943 spin-on filter (9-micron at 99% efficiency) to trap debris before it reaches the tank.

Key Features & Benefits

• Superior debris protection — Safeguards injectors, rails, lines, and tank from CP4 failure contamination.
• Extended driving range — Many owners can continue driving (sometimes significant distances) after a failure until they can get to a shop.
• Improved CP4 performance — Supports better output past 3,000 RPM.
• Easy, clean installation — Bolt-on design with OE quick connects (approx. 4–5 hour install time). No special cutting or permanent modifications required.
• Universal fit — One part number covers all 2011–2025 6.7L Powerstroke Super Duty trucks (F-250, F-350, F-450, F-550).
• Premium components — Billet aluminum construction with rubber isolators to minimize NVH transfer.
• Made in the USA by fuel system engineers with decades of experience.
• Proven design — Thoroughly validated in real-world testing; the original S&S kit protected thousands of trucks.
