DDP 2011-2016 GM LML, CP3 Conversion Kit w/ 12mm Pump – D05-F01-CCK-12
DDP LML CP3 Conversion Kit w/ 12mm Pump.
There is no doubt that the CP4 pump found in the LML Duramax has proven to be less than desirable. 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 that will cost several thousand to repair.
#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 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’s output is also considerably higher, which makes it a great upgrade if you’re looking for more hp.
This kit contains everything needed to swap from a CP4 set up, to a CP3 set up. CP3, lines, fittings, hoses, clamps, adapter plate. Made from brand new CP3 pumps, using the best practices and tooling in the industry, you can be confident you’re getting the best CP3 on the market for your truck.
Backed by a 1 Year Unlimited mileage warranty against defects.
The 12mm CP3 can support power above 1000hp with supporting mods.
No Core Required.
