Can you attach a picture of the line to which you are referring? I think it may be the vacuum line that comes off the cylinder and then goes back up to a useless air regulator under the seat that ties the air system together. I took mine off completely when I coastered and plugged the vacuum port and it made no difference and is merely a part of the emissions system if I recall. I think the fuel lines come off the petcock and cross each other and then go to the carbs prior to the point where you would see them from the right side of the engine. I am thinking it is the vacuum line that has burned on the cylinder...
I replaced my vacuum line initially and then did away with all the CA emissions stuff shortly thereafter!
