Full Answer

The type of cylinder determines how a company fills it. Companies normally fill the 20-pound tanks by weight and tanks for forklift fuel by volume. Some companies charge by the tank, so if customers bring in tanks that are still one-quarter full, they pay the same price as customers who bring in empty tanks. Many retailers offer exchange tanks, allowing customers to bring in their empty tanks, pay a fee and leave with full tanks.
