The vacuum line from the air pump located on the bottom right of the engine has come disconnected, on the other end, and I can't find where the line attaches. I have a 85 380 SL. It looks like it attaches somewhere on the top of the engine but where? I've looked at diagrams but they don't give a location for the components. Is there any photos of vacuum line locations?

 

normally it would attach to an air shut-off/blow-off/diverter/by-pass valve called by various names. you might look under the exhaust manifold. go to autohausaz.com and go to your model of car, go to emmisions and click on air/smog pump check valve to see what it looks like.

 

Thanks for the info but It's the other end of the vacuum line that came unattached.

 

you don't see a solid pipe coming out of the block and going under the exhaust manifold? my sl is a 129 and is not the same engine, but generally they should be simular in emission control. mine comes out just above the exhaust manifold mid-engine and goes down and under the manifold to the by-pass valve then to the pump. you might want to subscribe to alldata.com. it can come in handy for things like this.

 

Can't find any solid line coming out of block. Do you have a photo?
