Just finished up and installed my gas filler tube. There is what looks like an overflow that exits the left side of the tube near the top. There is a corresponding hole in the outer fender directly across from it that looks to be where the tubing that connects to that overflow passes through. Where does that overflow tube go? Does it just dump to the ground

, or does it connect to the plastic expansion chamber behind the left headlight. I cannot tell from either one of these schematics where the overflow goes.
