The engine that hubby and I just swapped out had the vacuum lines totally wrong, so I spent a good hour or two reading that @#$% diagram that's on the inside of the hood, but there is one that I couldn't figure out. This is an 86 EA82 (manual 5sp.tranny) and it's the only small outlet on the drivers side of the air cleaner coming out the bottom at an angle towards the drivers wheel. I have no clue where it needs to go and couldn't decipher that on the diagram. Anybody know which one I'm referring to and where it goes?

That is the Fuel Tank Vent line that runs into the hard line on the air box, around the airbox to the evap canister.

 

So its not a vacumn line. It being unplugged doesnt really hurt anything.

 

If its the hard line thats not hooked the airbox (below between the disty and the intake manifold) that is the vacumn advance for the disty. That does need to be plugged in
