The dealer made sure to test drive my car before and after. Yeah like that was needed.
Anyways, pn 84404473 is the part on the invoice. Also, they said a new bulletin came out yesterday for this and they stated that they replaced the line pursuant to that bulletin. I assume to get paid from GM. They were still so uncertain that they called GM for more info. That bulletin is 23-NA-207.
Hopefully this ends it.

My dealer also told me about the new bulletin after they replaced the line yesterday. The advisor said the job took the tech a little over 2 hours while the standard time was over 4 hours. The exhaust has to be dropped down to access the connection to the HPFP line under the dash. It appears to finally be quiet now.
