It could be the carb flout bowl drain hose. There should be a 1/2 inch of molded down pointing drain thing on the bottom of the float bowl.

48 and 49 should be on the end of the hose if that is the hose im talking about.
If that is the hose, you can always open the carb drain bolt(just turn it out a few turns, don't actually take it out), and watch to see where the gas runs out from. That will tell you where it belongs.
