A fuel tank has a filler pipe to which a vent pipe is attached on one end and which divides into two openings on the other end within the fuel tank. One opening is positioned below the other opening relative to the top of the fuel tank and has means for preventing expulsion of fuel through the vent pipe when fuel tank pressure exceeds atmospheric. The other opening is positioned to be in vapor even when the tank is filled to maximum capacity. Fuel vapor vents through the openings during refueling until fuel entering the vent pipe through the lower opening blocks the flow of vapor, thereby limiting the fuel level within the tank.
