I just put a used Holly 600 carb on my 71 Chevelle but I am not sure about something. I am not sure what the tube sticking out the front left side, at the top of the carb is. I know that the gas goes in the front right side of the carb. I have started the car and there is no air going in or out of this tube. I was woundering if someone could tell what this thing is and if I need it. This tube is right across from the gas tube.
