So for those that haven’t bought yet, get the 2021. The 2021 (verified just a little while ago) has the CP3. So no need to deal with a recall etc.

[MOD EDIT:
Any complaints or rants about the CP4 may be messaged in one of the other three or four threads along those same lines or the following thread:
PLEASE stick to the technical, TSB, and/or recall aspects of this issue.
This is not directed at the OP, it is intended for those new to the thread]

Viper67....are you able to point me to a link for this? I’ve seen a lot of conflicting information on this topic and would love to see something that totally confirms. Thanks!

I also saw this on a facebook group im in. Guy posted his 2021 limited and it sure looks like a CP3 in it. I have a 21 coming, and that is huge good news to me!

Videos of different fuel pump (other than CP4) for 2021 HD keep popping up on FB. They sure do look like CP3 but no one able to provide proof yet...

I can’t post a video here so I put it on Facebook 5th Gen forum. This was my 2021 6.7 limited.
