[MBZ] 1981 300SD Vacuum System Diagram Needed

[Kevin Beswick]

This is the '81 that I bought for my son.  The starting problem was the 
result of bad glow plugs.  Replaced those, and it starts fine.  The 
present problem is that every plastic or rubber hose is shot.  I've 
replaced all the fuel lines, but most of the vacuum lines fell off on 
their own, and I have no idea what they all go to so I can replace 
them.  Any ideas?
