OK all you knowledgable people WHY have we not heard about CP4.2 pump failures like we used to??????

All mfg have upped the fuel filtration systems. The CP4.2 does not like any moisture. All diesel fuel contains some moisture and contaminants.

Higher pressure pumps simply can not handle contaminated fuel. You cant fix the fuel problem so you must be able to treat the fuel problem.

yeah well what about all the 2011-2013's driving around with OEM filtration for that MY? where's the catastrophic failures?

I am not going to answer it for you but a simple Google search will find your answer.
