We all know the 2011-2016 LML Duramax features the CP4 injection pump which was supposed to be an "upgrade" over the CP3 units on the 01-10 Duramax trucks. This is certainly the opposite as it doesn't flow as well as the CP3 and the design can cause a catastrophic fuel system failure. When it does fail, it will send metal particulates throughout the entire fuel system and destroy injectors, rails, lines, etc.
