Ford 6.7L CP4 to DCR Pump Conversion Kit

The CP4 has a well-earned reputation for failing without warning, creating sudden power loss, and taking out the expensive high-pressure fuel system in the process.

Removing the CP4 is the obvious solution, yet developing a durable plug-and-play CP4 replacement with OE fit and function is the game-changing catalyst created by S&S Diesel Motorsport and PurePower. Starting off with a proven Stanadyne DCR fuel pump design, a joint team of S&S and PurePower engineers developed a variant specifically for the Ford 6.7L Power Stroke that matches the CP4 output curve and does not require any calibration changes. Combining that with OE-grade braided hose and steel fuel lines gives Ford Super Duty owners a more-reliable CP4 replacement that looks and performs like original equipment.

The two-piston DCR pump is based on a compact and modular design for easy integration, has low hydraulic and acoustical noise, features ultra-fast response times, and is biofuel and low-lubricity fuel compatible. It uses a patented eccentric drive pumping technology for increased performance, efficiency, and benchmark durability. The pump can provide a max fuel delivery of 1,250 mm3 per revolution. It also comes equipped with Stanadyne’s new corrosion-resistant inlet metering valve (IMV) designed to extend DCR fuel pump life. The IMV uses high-quality corrosion-resistant components and proprietary features to prevent large debris from entering the valve, providing exceptional robustness for longevity and durability in harsh environmental conditions
