Where does the hose for the fuel tank pressure vent go? I don't have a hose on mine and it would appear that fuel leaks out of that nipple when the tank is full. I have tried to look through the tech data and the various manuals on line, but the diagrams don't seem to be very clear on this hose's termination point. I put a vacuum line cap on it for now, but would rather it be connected properly. Thanks in advance.
