I've got old metal 5gallon pressure gas tank that has old gas/oil in it. The gas it close to two years old, and the tank is 3/4 full.<br /><br />I'd like to empty the tank, if I can just get the gas into a bucket (like the ones you use for changeing the oil or a car/truck) I can get rid of it.<br /><br />Whats the best way to get the gas out of the tank without making a mess?
