Is that hose loose or is it plugged into the bottom plate of carb

The one in my first pic is loose and i need to see where it runs

the one in that last pic with the blue F fitting i believe that is running to the purge TVs or canister

There is a hole in the carb under the TPS connector and a little to the right as I recall. Start engine and see if you can feel around for vauum

It may be the port for the Vacuum sensor that should be mounted on the passenger side front inner wheel well.

Just like with wires, a GM service manual would be one of the best sources to se how the lines are to running. Good chance an p/o might of change the routing of a few.

Yep, these cars are very prone to being screwed around with by POs that had no idea what they were doing.
