Because the air and fuel vapor in the tank , When refuelling, they will prevent fuel from flowing into the tank , Therefore, a vent pipe is arranged at the top of the fuel tank to allow air and fuel vapor to flow out for refueling . The height of the vent pipe is consistent with the maximum capacity height of the oil tank , When you add it to the maximum capacity position, the oil level just blocks the vent pipe inlet , Cause gas blockage on the side of the filler pipe , Cause the refueling gun to jump , Tell you it's full .
