Easiest way, if you don't have a pump, is to shove a bunch of the hose down into the tank, plug the end, pull the house out (the gasoline that flooded the hose when you shoved it down into the tank will stay inside, since you're not allowing air back into the hose), and shove the plugged end into the other container (preferably at a lower height off the ground), then unplug the end of the hose. Gravity will start the fuel in the hose flowing, siphon action will keep it flowing.
Trust me when I say, you DO NOT want a mouthful of gasoline! :whiste:
