Need help with this part. I have no idea what it is or what it does. It is on the passenger side engine compartment backed up to the firewall. It has 2 steel lines connected to it that are about the size of fuel or brake lines. It also has a larger diameter rubber hose connected to it that is connceted on the other end to a T that is screwed in to the head below the Carb. It is on a 63 Willys CJ5 with the F-134
