Fuel vapor emission preventing system
 A communicating pipe for introducing atmospheric pressure to an air vent circuit changeover valve has an intermediate portion provided in a fuel tank and slanted portions extending obliquely upward. The intermediate portion has a drain pipe wherein a drain hole is provided. Liquefied fuel in the communicating pipe is gathered to the intermediate portion through the slanted portions and drained from the drain pipe into the fuel tank. Thus constituted communicating pipe prevents a clogging of liquefied fuel in the communicating pipe.
