Does anyone know where the WUR vac lines connect two? I think I have two lines on my warm up regulator. Also, is there suppose to be a vac lin coming from the air breather hose that attaches to the air cleaner? My hose has an opening as if a vac lines goes there, if so, where does it connect to? I have the W116 chasis M110 inline 6.

Thanks

Does any one know where I can get a diagram of which color vacuum line goes from and to what on my 1976 450sl.

On the WUR, you should have just one vacuum line, which goes to a port on the bottom of the intake manifold. Additionally, there should be two hard fuel lines and one electrical connector.

I have the same breather hose on my M110, but the extra port is plugged. It is obviously for an option, but I can't say what. I think the option is rare. When you buy this hose new from the dealer, it comes with the port plugged.
