I was looking under the hood and found a vacuum hose disconnected but I can't find where it goes. the end of the hose appears broken off, not cut but there isn't any hose I can see in the vicinity. It is connected to a canister. see pictures

You are so zoomed in that it's hard to say what part of the engine you are showing me.

Is that the Passenger's Side of the engine compartment?

It looks like the windshield washer hose.
its on the passenger side and connected to a canister. the other hose to the canister is intact and goes to a vacuum source.
I've got the V6, so things look different for me under the hood.

But, my vacuum hose from the canister goes to a connection on the intake tube. I think your 91 uses a round air cleaner, so look for a connector on the bottom side of the air cleaner housing.
what is that canister for?
You got me. The best I can tell, it is filled with charcoal to clean the gasoline fumes before they get back to the fuel tank. I'm not sure, though.
