CP4 to CP-ISB21S3 (revised CP3) change for 2021 6.7L Diesel Trucks -- Merged Threads

[Thorvald]

Well maybe then we can retrofit this from the dealer without losing warranty. Of course this should be a voluntary recall or at least a service procedure should a customer have a problem with the old pump.

Be interesting to see if they leave us CP4 suckers as orphans. I knew better going in, and bought it anyway.

Wonder if Cummins pushed FCA back to the CP3.

I’m still waiting for 100% verified proof posted on a forum and not a blind engine photo, tried searching for the video on fb and couldn’t find anything because the “group” is private

 

[saltman]

Please post the video viper67, can’t find it on fb and thanks for the info!

Is there a recall for the 19 and 20s?

Unless NHTSA forces it, I don't see RAM recalling them. Like any good corporation, the cost of the failure rate is a lot cheaper than replacing all the ones in the '19, and '20's.

+1 for proof. My 21 is tentatively scheduled to be delivered tomorrow, so I’ll be popping the hood and taking pictures. I’ll share anything I find one way or the other.

It would be interesting to see if EPA would allow a retrofit, as it was approved with a CP4. Wood stoves for example are regulated on replacement parts without recertification.

That makes two different trucks now, the other was gray this is very convincing, they both also had the black/gray excess paint on the pump body

Salt man I have seen 3 different trucks outfitted

I’ll be jumping for joy if the HO trucks got it as well, just realized the gray truck on fb was not an HO

My thought exactly, all so far I've seen have been SO.
Really hope fca didn't choose the hp/tq war bs by keeping with the higher pressure the Cp4 is "capable" of.

 

[saltman]

Just our 2020 luck the so will be the only with it lol

FCA and Cummins will be like two cats scratching in a litter box trying to cover up the CP4 turd.

 

[DontSlamMyRam]

So when FCA leaves us CP4s hanging in the breeze, will it be cheaper to swap or just trade in the 19 for a new one? Assuming this is reality? I imagine paying a tech to swap in CP3 is $4250?

 

[2Many12Valves]

If this is true and my HO shows up without the CP3 It will stay on the lot.

 

[RV_Goose]

Interesting.

I'm going to jump in on this post, and hope to find out about any "recalls" early. Build date 2-20, so the worst of the worst when it comes to a Fuel Pump. I'll probably never put more than 7500 miles a year on mine so will only have 40K on the truck when the warranty runs out in April of 2025. I'm super picky about the fuel I choose, and drain the separators after each trip I take with my RV. I just don't want to get stranded on a trip with my 5th wheel hooked up. I LOVE everything about the truck, and it does exactly what I need it to do. It just makes me a little ILL thinking about my CP4 turning into a shrapnel bomb, blowing the end off one of my ejectors, taking the motor and everything out 800 miles from home. HELLO FCA!!! Ram Cares, Chime in and give me some good news about your plan to make my truck reliable!

 

[Cummins3]

Anything ram cares??? Even a confirmation on when the switch happened
