S&S Diesel Motorsport CP4 to Injection Pump Conversion Kit

The S&S Diesel Motorsport CP4 To DCR Injection Pump Conversion Kit is engineered to resolve the prevalent failure issue of the CP4 high-pressure fuel pump in Ford Super Duty trucks equipped with the 6.7L Power Stroke diesel engine. This common failure can result in sudden power loss and extensive damage to the entire high-pressure fuel system, with repair costs potentially exceeding $10,000. This kit offers a direct, plug-and-play solution by replacing the problematic CP4 pump with a robust DCR fuel pump from PurePower Technologies, Inc., based on a proven Stanadyne design. The DCR pump variant has been specifically developed for the Ford 6.7L Power Stroke, matching the original CP4 output curve without requiring calibration changes. It features a two-piston design for easy integration, low hydraulic and acoustical noise, ultra-fast response times, and compatibility with biofuels and low-lubricity fuels. The DCR pump can deliver up to 1,250 mm3 of fuel per revolution, which is 25% more than a CP4.2, providing ample flow for worn injectors. Installation requires the removal of any previously installed S&S CP4 bypass kit, as it is not compatible with the DCR conversion. For 2011-2016 model years, a Vacuum Pump Mounting Gasket (Ford Part # BC3Z-2A572-A or Mahle B32630) is required; this gasket will be included free of charge if purchased from the seller. While a new driver-side fuel rail is typically not needed, underlying issues such as debris in the PCV or loose internal rail components on higher mileage trucks could potentially cause issues and may necessitate rail replacement. The S&S Diesel Motorsport CP4 to DCR Pump Conversion is emissions compliant (CARB EO # D-756-7) and fits 2011 to 2024 Ford F250-F750 diesel trucks. It is backed by a two-year, unlimited-mile warranty, offering peace of mind and potentially saving owners significant repair costs.
