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.

So I wonder if CUMMINS made RAM change the under bed filter from the spin on RAYCOR to the new canister system for this reason?????

Why did Ford deny claims?

[stsmark]

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.

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.

[blofgren]

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!

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.

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.

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.

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?

LOL try .2, have you heard of any issues with the CP4.2 pumps? Nope you haven't, nice try though.

I'm not sure it will actually tow grades any better. I'm right in the power band on certain grades with 4.10's. Only issue is when things get down in the 25-40 range where the revs go ballistic at times. That scenario and the big drop off on acceleration should be solved. Issue is the power is the same.

When I had my 08 F150 5.4 3.73 4sp AT I ran up one mtn pass in 3rd (1.1) I latter got a 2010 5.4 3.73 6sp. Ran up the same grade in 4th (1.1) at the same rpms.
