I have a feeling the port that has no hose attached is the distributor vacuum connection, and the one you have indicated below it connects to the EGR valve on the side of the manifold.
RIGHT! but NONE of them pass air. I don't know if someone blocked them, they just clogged up, or if they are supposed to be that way. the breather line from the valve cover for instance, WHY would that not pass air? that would make no sense- and a vacuum advance can't work if it gets no vacuum.
