Abstract
A natural gas fueling system is set forth for filling one or more vehicle tanks from a supply such as a storage tank or a main gas line. The system includes at least one hose assembly having one end adapted to connect to a tank and the other end having a female coupling. Also included is a dispensing assembly having a manually operated valve to control the flow of gas from supply. Connected to the valve is at least one male coupling adapted to be releasably received by the female coupling. The male and female couplings permit the hose assembly to be pulled and disconnected from the dispensing assembly to prevent damage to the hose or dispensing assembly. Additionally, the couplings are provided with check valves to stop the flow of gas when disconnected. A vent is provided to vent any leaking gas as is a locking structure to lock each hose assembly to prevent unauthorized use.
