If your YJ is like my CJ-7, the "extra" line should be the fuel return line that goes from the fuel filter back to the tank. Make sure that's what it is so you don't hook it up to a line that goes to the charcoal canister or something else. Not sure about the air cleaner. Does your YJ have a Carter BBD? Then there should be a bolt comming out of the carb that the air cleaner also attaches to. DO NOT TRUST MY INSTRUCTIONS! I'm just going by my CJ's engine compartment. Hope this helps and doesen't hinder. Good luck!
