Motorcycle mechanic here... venting equalizes air pressure inside and outside and the vent should NOT leak fuel IF the tank is NOT filled to the top on a hot day. On a hot day, fuel will expand in the tank and come out the vent if the tank is topped off. Think the spare tank in question will be the same. I do motorcycle carburetors and if a bowl vent is capped off, the carb floats go nuts and puke gas or won't allow flow. They sure won't work right with the vents plugged.
