I was thinking that same. I would have expected the non serviceable CCV to be used.

Could be they replaced it with what they had on hand. There are still plenty of them sitting on the shelves. Good to hear it was a simple fix too. The explanation sounds reasonable too. It was probably just under the threshold to trigger a code.

Guys, I didn't know there were different versions of the CCV. I will email the service manager and ask for a clarification.

Thank you.

change over to the DCR. Why did they both quit on you?

Water, DEF or what was the cause.

This is why many of us have an s&s DPK

wont prevent a cp4 fail but will protect the rest of the fuel system from cp4 fragments.

I wonder how many of these CP4 failures are from people that don’t know any better and don’t understand what they are doing to their high pressure fuel pumps.

I dissent. The CP4 is notoriously intolerant of water. The CP3 and HP4 pumps do not have better operators. They have better designs.

There is no doubt that the CP3 is more robust than the CP4 however there are a lot of high mileage 6.7s out there with no fuel pump problems. Running the CP4 dry is a big no no and I have seen it done time and time again. Also you really should not be seeing water at you high pressure pump if you’re staying on top of your filter maintenance like you should.

I made a comment on his video yesterday about how stupid he was to do what he did. Not only letting it run out of fuel but then cranking and cranking on it. ANYBODY that doesn't know how to cycle the key 6x to get the air out needs to just sell their truck............. Even if they pay someone to change the fuel filters they should have read the manual..

I dunno. Some operators may need a little help.

The thing is a few weeks or months down the road when his CP4 fails he will say I had the fuel filters changed every X number of miles and done all the required maintenance, I just don’t understand. I’m sure there has been some failures for no reason but my point from my original post how many have failed from this kind of thing? I’m sure if this guys pump fails this day will never crosse his mind.
