CP4.2 Carnage Esada!

[DonFitzwater]

Nah, pure clickbait.........These are the fuel filters from my 2019 at 14,159 miles. Not a spec of anything in the engine mounted filter and only some slight sediment on the top of the primary by the tank. I was fully expecting some metal fragments but no such luck.

 

[promisedland]

Haha! Nice job.
Yah made me look.

I just changed my fuel filters for the 2nd time at 20,000. Same results as you Don. Both times no metal or sediment

 

[nukegm]

LOL - click bait. filters look nice. cheers comrade !

 

[Cummins12V98]

Sure nice having such a good filtration system.

 

[DonFitzwater]

Was it R.Taylor that had some metal in his filters when he changed them?

 

[jacknife]

Just changed mine for the first time one year 11,000 miles . Nothing !

Would the failure of the fuel pump show up in the filters? If the pump blew and the engine died before sucking any fuel back through the system?

Don,

I believe you are hands dow the winner of the 2021 Chicken Little Award. Good job baiting the trap.... you snagged me.

Andy,

I'm certainly no expert, but there have been reports of folks finding shiney specs of metal in there first fuel filter from the tank. I've not seen a post where one exploded or had catastrophic failure. That whole mess has had some contentious "discussions" here on the TDR about how broad the problem really is, but I guess it was big enough for Ram and/or Cummins to go back to the CP3.

I'm sure there's some folks out there who have had the big failure or have direct knowledge of those who have.

Cheers, Ron

Yes I believe R.Taylor reported some metal in the primary filter.

Pretty sure the pumps don’t die quickly....they make metal for a bit and then kaplowy! The filters get metal through the return of fuel from the injection system in theory.

Ooooooh now you got me thinking!

 

[bcbender]

yeah... you could post that FCA is swapping out all 19/20 to CP3 and boosting power to 425/1100.....

 

[R.Taylor]

Yes... I had glittery floaters in the bottom of the rear bowl on my first filter change. I have not pulled it back off for a look... Kinda don't want to plus I could jinx myself and my pump will toss me the middle finger far from a dealership.

I fully expect this one to grenade far from home when it's really cold or blowing snow. I'm terrified but keep driving it!!!!

I had some good Mexican food yesterday in Borrego Springs, CA.

 

[endoscott]

Borrego Springs! We love that area!

 

[endoscott]

But you definitely don't want to blow up your CP4 down there.....
