The LML Duramax powered 2011 to 2016 Chevy Silverado HD and GMC Sierra HD trucks. It brought piezo injectors, the Bosch CP4.2 pump, a 9th injector for DEF and a much stronger chassis.

LML Duramax FAQ

What is the 9th injector on the LML?

It doses fuel during the DPF regeneration process, separate from the 8 main cylinder injectors.

Is the LML CP4.2 pump a concern like the Ford CP4?

It can fail similarly and contaminate the fuel system. Many owners add filtration or a lift pump for extra protection.
