If you want to extend the life of your LML by getting rid of that CP4 pump or hop up the performance then this S&S Diesel CP3 conversion kit may be the unit for you. CP4 high pressure pumps are the Achilles heel of the LML Duramax engine because of high failure rates, and commonly taking out the entire, very costly, high-pressure system with it (injectors, rails, lines).
They even offer a 50 state legal conversion along with competition use options. The CP3 pump just has the proven history that we've come to expect with our diesel trucks.
Part Number: LML-CP3-CARB

Ask a Question-
How difficult is the cp3 conversion to perform in my 2011 LML?
6/10. Solid mechanical and diesel fuel system knowledge and specialized tools required.
-
What is the difference between the pump that needs tuning and the one that does not ?
Tuning required = more performance-oriented, requires ECM updates. No-Tuning CP3 = plug-and-play, retains stock-like functionality for an easier swap.
-
Hey do you need a cp3 core for the 50 state legal swap?
There is no core charge on this, you don't need to send anything back.
