There have been a lot of guys having problems getting one pound of propane into a one pound tank when refilling. I made this video a few days ago to show how to do it. Only use this method with
completely empty 1LB tanks. Don't try to refill a partially empty tank or you WILL over fill it and have major problems using it in your lantern or heater.
