ABSTRACT:
A venting valve for a cargo hose includes a cover plate attachable to the hose, the plate having an opening which receives a coupling to a check valve. The check valve prevents escape of fuel but admits air to permit fuel to drain from the hose into an attached storage tank, preventing spillage when the hose is subsequently detached therefrom and handled.
