I have looked at the vacuum diagrams, but my problem seems to be outside of the normal diagram.

I was cleaning the Benz so I could take my wife out for dinner last night. Before I went in to shower up, I took it for a quick run. All was fine.

We go out for dinner and park and it does not shut off. I tried a number of vacuum lines but all seemed OK, so we let it run while we had dinner.

Got home and the only way I could shut it off was dumping some Sea Foam in and covering up the air intake.... good night....

This morning I get up to look at things. I see a brown/black vacuum line not connected and I see no open connections. It goes back to the cabin. All of the diagrams show the engine compartment and not the cabin vacuum.

I have tried to plug just about every line I can think of.

How does vacuum stop the diesel? What the hell am I doing wrong????? The only way I can stop this thing is to Pull the fuel line.
