ABSTRACT:
In an air breather system for the fuel tank of a vehicle, a mechanical seal is provided at the mouth of a filler pipe for preventing overflow from the mouth when filler gun is inserted into the mouth for fueling. The mouth is communicated with a canister for adsorbing the vapor of the fuel through an air breather passage. Even when negative pressure occurs under the mouth, normal fueling is performed without functioning the automatic stop of the filler gun.
