Locate propane filling stations nearby by searching your local yellow pages. Consider local convenience and hardware stores as well.
Call the station to make sure it refills consumer propane tanks. Some companies only handle commercial sales. Check first.
Drive to the station. Remove the propane tank from your car, and carry it to the attendant. If this station is in a convenience store, go inside without the tank and let the clerk know you need assistance with refilling your propane tank.
Watch the attendant refill your tank. Stay a safe distance away. Propane gas is under a lot of pressure, so follow the attendant's instructions carefully. You can't refill the tank yourself because of the associated dangers.
Take your propane tank from the attendant once he refills it for you. Place it back in your car in a secure position. Pay for the service.
