L5P Duramax CP3 Conversion Kit

The S&S Diesel L5P Duramax CP3 Conversion offers a robust upgrade for competition-focused L5P Duramax engines. This kit replaces the factory CP4 pump with a modified Bosch CP3, known for its durability and consistent fuel delivery. The S&S-modified CP3 pump is engineered to maintain linear output and efficiency across the RPM range, up to 4,000 RPM, ensuring reliable performance under demanding conditions. This conversion is compatible with the factory supply pump and is available in three configurations: 10mm, 12mm, or 14mm stroker CP3 options, allowing for customization based on specific performance needs. Each unit comes with a comprehensive test report, verifying its performance. The kit is designed to fit 2017 to current GM trucks equipped with the L5P Duramax engine. Installation of this CP3 conversion requires engine tuning and is intended for competition use only. The kit includes all necessary hard lines to connect the CP3 pump to the factory fuel rails, along with feed and return lines. Buyers are advised to download the installation instructions prior to beginning the process.
