It is just a vacuum reserve tank. So that when the vacuum in the engine goes up and down, there is enough volume to run things during the low times.

If you plug the hose off the only real thing you might notice is during hard acceleration the heater control doors might flap to the default location then back when the vacuum improves. You fixed the leak in the hose by shortening it, as long as the round tank does not leak also you are good to go.

its just a vacuum reserve. without it you'll loose ac/heat flow etc on acceleration.
