Why is a (new) return line sweating?
On my '85 300d....
Changed all the return lines a month or so ago. I noticed a slight diesel odour on a hot day and found the longest line, the one from the first injector back to the filter head, is sweating for the first 1.5 inches from the injector.
I have never had this happen to a recently replaced return line. Is it an indicator I damaged it on the install, somehow?
