[Dead Parrot]

It looks in the pic that there are two sizes of lines being joined. I think the smaller line with the 90* bend is the original. You need to trace the larger line and see if there is a matching compression joint somewhere else that goes back to the smaller line.

Probably should put replacing that on the list of things to do. If it fails during an accident, the investigation might assign blame to that failure and leave you liable even if the other driver caused the wreck.
