ABSTRACT:
A first valve body has a tubular portion which releasably connects with a second valve body, and each valve body defines a center fuel supply passage in which a movable valve closure member is spring biased against an annular seat. Each valve body also defines a set of circumferentially spaced arcuate fuel vapor passages spaced outwardly from the corresponding fuel passage, and corresponding vapor passages within the valve bodies are connected by an annular chamber within the tubular body portion. Each fuel passage receives a closure ring which cooperates with an internally threaded end portion of the valve body for threadably receiving a coaxial fuel fitting, and resilient rings form fluid-tight seals between corresponding fuel and vapor passages.
