So you think the vacuum system is confusing... well count your blessings your MBZ is an 81 model!

I think your POST above might have been missed by Brian Carlton and others who watch and often respond to this subject... so hang there and someone will see ya and help out. I'm away from my cars on a road trip and canNOT be of much help. If you have not discovered it, check out the website: http://peterschmid.com/ as a source of engine/tranny vacuum diagrams... follow the "Vacuum Schematics" links !

It can be difficult for some models to find the correct vacuum diagram and your year might be missing... but see if you can tell if the diagram at this weblink is for your car: http://peterschmid.com/vacuum/1977_1985/617_95/1981_1984.jpg

Give this THREAD a chance for it might take a while for others to discover your plight [whatever it is] and the more specific your question, the more impression you leave that you have done some homework... and thus the more likely someone is to pitch in and try to help you out... especially if your car is the likely automatic tranny model.

I'm out of here for now... suffering Jet Lag in TN,
Sam
