The .2 doesn't mean revision, it means that it is a two piston pump. CP4.1 one piston, CP4.2 two piston.
Yes, internet is full of CP4.1 and CP4.2 failures, I think you already know but just choose to think its ok because Ram/Cummins is now using it... unreal!
I have not heard of anyone having any problems with the .2 pumps. I have one in my Ecodiesel and it is in Ford and GM diesels. When Ford came out with the 6.7 PS both Ford and GM had many CP 4.1 pumps fail.
Then Bosch went to the CP 4.2 and no more failures. At least not like we where seeing with the .1 pumps. Are there .2 failures, yes but nothing near what the .1 pumps where failing.
The difference is Ford flat out refused to protect their customers and GM stepped up and warrantied their trucks.
I would not think twice about buying a diesel with the CP 4.2 pump no mater the maker.

LOL..... Your wrong as usual. Ford and GM (used to) only uses the two piston design CP4.2 pump.
Did you not read Bigfoot response?Perrysburg Dodgeboy wrote:
The .1 is single piston (used in smaller motors such as the VW) and the .2 is a 2 piston for larger motors such as the GM/Ford, and now Ram HDs. The .2 IS NOT a revised pump... Just a 2 cylinder pump.Bigfoot affair wrote:

They all have catastrophic failures that cost about 10K to repair.
GM quit using them around 2017. They paid out a LOT in warranty claims. For did not pay out so much, as they denied a lot of claims. They still use the CP4.2.- What he said ^^^^^^^
- As much as the failure rates on the newer trucks may be less, I firmly believe that as the miles rack up and years tick by the failures will once again occur. This may not be an issue to someone who buys new and sells off their truck every few years but it certainly is to the people who keep them long term. And when they fail, they take out the entire fuel system. The same can be said about the CP3 pump, but the engine simply quits; replace the pump and carry on!
Myself, I plan on keeping my truck a very long time so this is an important issue for me. I can see the day where trucks will hit the boneyards early because the cost of replacing the trashed fuel system is more than what the truck is worth. blofgren wrote:

We had our first 93 RAM/Cummins for 7.5 years, the second 2001.5 14 years and will keep the present 2015 until they take away my drivers license, which is hopefully 10-20 years out or maybe a little more.
CP3's have on "some" occasion taken out the whole fuel system.- OK all you knowledgable people WHY have we not heard about CP4.2 pump failures like we used to??????
- It's a good thing they don't alcohol in these Forums!

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.- I think part of the reduced fail rate for Ford is in 2015 they changed from Piezio to Solenoid injectors. Changes in the nozzle allowed them to drop the max pressure from 28k to 24k.
- Why did Ford deny claims?
