Hello! Can someone please tell me whata that is for a line at the front of the lock carrier? It runs from left to right, comes from the fender to the left and ends on the right just before the headlight in a check valve. Can this be a vacuum/pressure line, which is responsible for the much too fat motor run? I just fell through the AU with timpani and trumpets. The hose/line has been torn several times and is only loosely attached to the connectors. B Help!
