DDP LML Emissions Compliant CP3 Conversion Kit w/ CP3 Pump

DDP LML Emissions Compliant CP3 Conversion Kit w/ CP3 Pump

There is no doubt that the CP4 pump found in the LML Duramax has proven to be less than reliable. These pumps have a tendency to fail for many reasons and when they do fail they send metal shavings into the fuel rails and injectors resulting in the need for a complete fuel system overhaul. #1 cause of failure is water or dirt contamination which is not covered under GMs warranty. In order to prevent this from happening we have developed a kit to convert the LML engine to accept and run a much more reliable CP3 pump that was found in the 01-10 Duramax. Not only could it handle more abuse than the CP4, it is 100% drop-in and go.  Support for the 9th injector comes from a new port machined into the pump housing.  This allows the pump to utilize the stock GM supply line.  No extra lines, blocks or jumpers to worry about leaking.  No tuning or extensive modifications needed for install. This kit contains everything needed to swap from a CP4 to a CP3.

Kit comes complete with CP3, lines, 9th injector supply line, fittings, hoses, clamps, adapter plate.
