Designed for high-performance and competition diesel applications, the S&S Diesel CP3 Conversion replaces the factory high-pressure pump with a proven Bosch-based CP3 platform, delivering consistent fuel volume, improved durability, and superior RPM stability.

Each pump starts as a brand-new Bosch CP3 core and is precision-modified in-house by S&S Diesel Motorsport for maximum reliability and output. The result is smooth, linear fuel delivery all the way to 4,000 RPM while maintaining excellent efficiency and drivability.

This conversion is fully compatible with the factory low-pressure supply pump and includes an individual test report verifying flow and performance prior to shipment.
