Missing hose?
Goes back to the gas tank on mine. I think its part of the vapor recovery for the fuel tank. EVAP emissions control system part. My guess is that it removes trapped fuel vapor as a safety precaution.
It should have a GREEN cap on it along with a tag that says it is the evap system test port that looks like this:

Get a cap for it, then leave it alone. IOW, don't randomly screw with it.
