Ever since I changed the fuel filters in my '84 190D I've noticed a whiff of diesel when idling or when first starting (which I guess is idling). I checked all around the new filters but couldn't find any leakage. Finally had the head slap moment when I realized it was the return lines which I've never changed. Put that on the "to do list" since it seems to rain all the time lately.
Today my wife took the car to work and complained that the diesel smell (which she surprisingly hadn't noticed previously) was really bad. Tonight after dinner I got lucky and the rain abated so I ran out and dug through my spares box. I found the viton tubing I'd bought to put lines on my '83 240D years ago and there was just enough left for this job. I even cut apart the end plug and put it into the viton. All back in place I can't detect any leaks and the smell is less so thats a win. I never did find a smoking gun on leakage, worst one was the rearmost but even that one wasn't bad, none were wet with fuel... One question, I didn't take a picture before dissassembly and I couldn't remember on the last injector which side took the return line and which took the plug. I ran it the most expedient way but it led me to wonder if it matters. I either got it right or it doesn't matter and I was reassured when pushing on the plug I could make diesel come out the return line on the next injector back... So, does it matter which connector goes where? -Curt _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
