Abstract: A device (10) for use in connecting unlike gas/liquid fuel containers (12,14) and transferring gas/liquid fuel between the containers (12,14). The device (10) comprises threaded first and second ends (28,34) and a central longitudinal bore (40). The first end (28) is adapted to threadably engage an industry standard outlet of the container (12) to mount the device (10) to the container (12). The second end (34) is adapted to theadably engage an industry standard inlet on the other container (14) to mount the device (10) to the container (14). A finger (36) mounted to and extending outwardly from the second end (34) is adapted to engage and open a needle valve of the container (14) to permit fuel to flow between the containers (12,14) when the device (10) is connected to the containers (12,14).
