WCFab CP3 Conversion Kit for 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks equipped with the LML 6.6L Duramax Turbo Diesel engine. The Factory CP4.2 Pump Found on 2011-2016 LML Duramax is known to be a problematic component. Even the slightest amount of fuel or water contamination can ruin the pumps internals leading to metal debris flushing throughout the entire fuel system. When these pumps fail it can lead to a repair job usually including all new injectors, fuel system sensors, fuel lines, and complete cleaning of the fuel tank and costing $8,000+. We set out to develop a solution for this issue and came to market with the first CP3 Conversion kit in 2013. This Made in USA kit combines our previous offerings into a single part number, providing improved compatibility with completely stock and lightly modified trucks, and provides an excellent value, 'no tuning required' solution when paired with a new Bosch OEM 'LBZ style' CP3 pump (sold separately). Kit includes: Black Anodized CNC Machined Billet CP3 Pump Mounting Plate, Precision Formed Pre-Bent CP3 to Fuel Rail High Pressure Fuel Lines for use With or Without OEM Filter Housing, CNC Machined Stainless Steel High Flow CP3 Feed & Return Fuel Fittings, Pre-Formed Feed & Return Fuel Lines for OEM-Like Fit and Finish, 9th Injector Fuel Lines & CNC Machined Black Anodized Billet Aluminum Fuel Distribution Block, FCA / MPROP Inlet Metering Valve Extension Harness, Low Pressure Fuel Feed Lines, & Installation Hardware. Supersedes WCF100711 and WCF100249.
