I have had my new (to me) E300D for about 5 weeks now, and have begun to perform the required maintenance. Oil, Fiters, Fluids, etc.

I noticed that the PO had not had the injector return lines replaced during his 6 years of ownership (and dealer maintenace). I can see some "cigar hose" peeking out from under that formidable intake manifold, so I know it's there.

Anyone hasve experience in installing new return lines on a non-turbo E300D?

I changed them every year on my 300SDL, does the E300D have a different requirement?
