Yes, Bob, I see your point. However, the vapour causes a blockage because the pipe from the tank to the carb is relatively narrow which allows a small vapour bubble to block it.
By the way, I should have mentioned that the open-ended vent pipe should be long enough to take the venting end above the top of the fuel tank. If it's shorter (eg below the fuel level in the tank) then fuel will come out of the vent tube when the level in the tank reaches that height.
