S&S Diesel Ford 6.7L CP4 to DCR Pump Conversion

Upgrade your 2011-2025 Ford 6.7L Powerstroke with the S&S Diesel CP4 to DCR Pump Conversion Kit! 

This solution eliminates the risky CP4 injection pump in favor of the more reliable CP3/DCR style system—moving return flow away from injectors and greatly improving fuel system longevity under high demand.

Simply replacing your factory CP4 with the S&S Diesel CP4 to DCR Pump Conversion Kit can save you THOUSANDS of dollars in repair costs.

Why Choose This Kit?

• Eliminates CP4 Pump Failure Risk — Switches to DCR/CP3-style system to avoid debris and low-pressure return issues inherent in CP4 systems. 
• Cleaner Return Routing — Returns shifted away from injector outlets, reducing heat soak and contamination buildup.
• Better High-Demand Performance — Designed for trucks with high horsepower or tuning demands, ensuring stable fuel delivery. 
• All OEM-Interface Connections — Uses factory-style connectors and fittings wherever possible for clean integration and compatibility.
