Does anybody know the part # for this line? From the oil filter housing to the oil pressure guage? 1980 300SD. Mine is starting to drip a little from where the plastic line meets the metal. Not where it threads onto the gauage, but right where the plastic line ends. That end fitting rotates freely on the plastic line.

Anybody ever fix that? I wonder if I can just cut it off and press it into the line again. Maybe with a little heat?

Otherwise maybe a plumbing compression fitting might work. Does anybody know what the thread dimensions are for the gauge?

It definately had a big leak prior to my owning it because I spent about 6 hours scrubbing carpet with dish soap to get all the oil out last summer. Do not want to repeat that! haha
