Abstract: An adapter is used for the removal of liquid contents from storage drums. The adapter has a bung body that threads into the normal bung hole of the storage drum and is sealed to the drum head. A hose fitting on the bottom of the bung body is connected to a suction hose that extends to the bottom of the drum. On the top of the bung body is a quick release, valved fitting. The bung body also has a vent to admit air into the drum as liquid is withdrawn from it. The vent is equipped with a spring-loaded check valve so as to be normally closed.

Abstract: A fuel can adapter is used for adapting standard fuel carrier cans for use as temporary fuel tanks for outboard motors and the like. The adapter has a tapered bung that fits snugly into the necks of all common fuel cans and a peripheral flange at the top end of the bung. The thimble supplied with the fuel can for use on the fuel can neck is threaded onto the neck over the adapter for holding the adapter in place. A fuel passage through the bung is connected at the bottom end with a nipple which is in turn connected to a flexible fuel suction line extending from the bung to the bottom of the can. At the top end of the bung is a conventional fuel tank coupling for connection to the coupling component on the end of an outboard motor fuel line. In preferred embodiments, the bung is equipped with an air passage and a check valve for allowing air to enter the can while preventing the flow of air or fuel from the can.
