1979 450SL vacuum line disconnected

There is a vacuum line coming from the right side of the engine compartment, 1 of 2, that is laying disconnected and there is no obvious place to reconnect it. The line is white plastic with a black rubber hose connection. Anyone have pictures of the connections? The online maintenance manual is very hard to use for this. Because of the length and bend of the line I feel it attached somewhere on the front left side of the air intake manifold. Thanks for any help. John

The white line with the black rubber end is laying on the hose

Thanks for including the picture. I take a look at my SL this weekend and see what I can see. It's a 73 so things may be different.

I would remove the air cleaner and follow the bend in the hose. i think there is a multi point vacuum connection under there

Thanks for that. Did that and still could not find a port. Took it to a garage Friday

Had the vacuum lines replaced at a shop in Ft Worth. Helped greatly with engine power
