Well if you maintain your fuel filter with a quality filter NOT the 3 dollar junk E-Bay/Amazon filters and also buy quality fuel you won't have a problem.

If you are that worried about a CP 4.2 failure than buy a gasser not a diesel. It really is that simple.

It's really not that simple for me, but it may be for you.

The failures of the early CP4's both 1 and 2's was the piston with a roller follower getting turned sideways to the pumps cam lobe. Bosch was unwilling to pay the holder of a patent to keep the piston from turning in the bore.

The Metal that contaminate the fuel system was from the roller and cam lobe.

They have been working to fix the issue.

This page shows a picture of a damaged roller. Fig 3

This may be the Edelbrock patent that Bosch was unwilling to pay royalties to use.

What do you consider early pumps?

2016 Ecodiesel cp4.2 failure Clicky

2016 Duramax cp4.2 failure clicky

2016 Powerstroke cp4.2 failure clicky

I could waste half the day posting this ****, they haven't made any changes to the pump to prevent the piston from turning in the bore...

Unless, Cummins installed a failure disaster device to save the rest of the fuel system... Aftermarket has them out for the Powerstroke Disaster prevention

Is there anything out on the aftermarket for the Duramax that operates as a failure disaster device? I would be interested in something that provides some peace of mind against a $10k repair bill.

adding a lift pump is your best bet. but spending north of $600 for piece of mind isn't something i'd do. if someone is that worried about it double the money a put a cp3 on the truck. 100's of thousands of these trucks are out there running without issue.

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.

so you don't know then

All three of my Ram trucks were taco born, believe. Can not really confirm that on the 93.

Extra cab most likely Mexican, regular cab most likely US.

I have owned 2 US Made and 3 Mex.

All three of my Ram trucks were taco born, believe. Can not really confirm that on the 93.

I don’t think I have ever said I won’t buy one but I never liked how people were denied coverage. I would not hesitate to buy a 2020. The good far outweighs the bad owning. RAM.

Good luck! :B

2020, even if they don't move production back to the USA?

Have no need to buy a new truck mine tows 33-35k combine just fine. But if in the market I would still buy a MEXICAN ASSEMBLED RAM with mostly USMade components.

2020 will be US Made
