there is a 1/8th inch hard plastic tube that comes out of the left front wall of the engine bay. If you follow this plastic tube, it should bring you to the valve. There is also a 1/2 to 3/4 inch rubber tube that comes out of the back of the engine (the part facing the front of the car) which also goes to the valve.
