How do I stop a tubular lantern from leaking oil from the air tube?
In use, lantern wick conducts heat into the oil, this in turn creates expansion, and will cause oil to overflow into the air chamber under the burner if the lantern has been overfilled. Once this happens, the oil will leak out of the joints where the air tubes go into the air chamber above the tank. To prevent this, only fill the lantern to just under the fuel spout threads. Use a small white plastic kitchen funnel to more easily see the fuel level when filling. As a precaution, place the lantern in a shallow pan when re-fueling. If overfilling occurs, empty some of the fuel.
