As long as you are putting diesel in your pickup that is from high traffic gas stations and regularly change your fuel filters then you really shouldn't have to worry about the CP4. The CP4 going out isn't as common as facebook makes it seem. If you are truly worried about it, skip the disaster prevention kit and get either the CP4x or the DCR pump.

The problem with modern diesels aren't the engines themselves but they way they are used. Guys used to be happy just buying a half ton to fulfill their pick up itch but now everyone wants to get a 3/4ton diesel. Modern diesels nor really any diesel engine are designed to be grocery getters (except TDIs maybe) where you crank the pick-up, drive 2 miles, turn it off, just to redo the process on the way home. A prime example of this is in the 2 years I had my ram 2500 before going to college where I was constantly pulling horse trailers and equipment with it, it never went into a regen cycle where it alerted me that it was cleaning the DPF. During my first semester, it told me my DPF was full and went into regen 3 times.

Diesel engines need to be worked and get up to operating temps on the highway regularly in order to clean out the DPF and other engine components. The CP4 is pretty much an engine in of it's self in my opinion, it's two pistons in cylinders compressing the fuel like an air compressor. Now this is just me speculating but if that doesn't get up to temp regularly then it is hell on the seals and it's equivalent of piston rings. Machines like to be ran, If you are just farting around the suburbs in your diesel 3/4ton with no hitch in the bed and a B&W in bumper hitch with out a sign of use on it, then you are just asking to have problems with your engine.

Sorry, Rant over.
