A tank closure apparatus comprising a housing adapted to attach to a tank. A filler-cap assembly seals a liquid filling port of the housing. Passageways carry liquid from this port to openings on a surface of the housing within the tank. A means, responsive to a pressure generated by a pressure generating device, which supplies pressure coterminously with the operation of a process or a vehicle propulsion means, causes a sealing member to cover the passageway openings, providing a seal should the operator forget to close the filler cap.
