m103 Vacuum Diagram anyone?

[smemolo]

I posted this over at Benzworld but it doesn't seem like the thread is going anywhere. I'm seeking an m103 vacuum diagram because I have a few hoses not connected to anything. I have a 1990 300E.



I was told this one was supposed to connect to the breather hose on the airbox, but I was under the impression that the breather hose was supposed to be connected to a Y splitter that had one line going to the fuel pressure regulator. If that's the case then I would need to know where this one goes.
