This CP4.2 bypass kit fits Ford F-250/F-350/F-450 trucks with the 6.7L PowerStroke diesel engine, model years 2011 through 2025. The CP4.2 bypass kit safeguards fuel injectors, rails, lines, and tank from CP4 debris by splitting the fuel supply 25 inches away from the CP4 pump and routing return fuel through a billet filter head. The kit includes a Donaldson P550943 spin-on filter rated at 9-micron, 99% efficiency.

Product Details

• Design: OE-style quick connect lines eliminate the need for cutting the factory supply line, which is a debris introduction point.
