I am not sure how the charcoal canister works. The overfill limiting valve is most likely pretty important.
I am guessing it is some sort of one way valve.
But you would not want to connect that tube that runs from the vapor separator to the engine bay directly to the manifold vacuum.
You would then have the petrol tank connected directly to the engine which would affect the way the engine runs and the vacuum could collapse the fuel tank. A backfire could blow back direct to the fuel tank and ignite the gas fumes and cause a major fire.
