I think there should be a little valve, like the one where you put air in your tire, somewhere on the fuel rail (that small silver tube that goes around the top of the engine and sits on top of the fuel injectors). Just depress the little thing like you were letting the air out of a tire, but protect your eyes, there might be a spray of fuel in your face!
