Abstract
A portable fuel dispensing system comprises a fuel pump assembly, a conduit, and a fuel tank cap assembly. The pump assembly comprises a handle assembly, a cylinder assembly, and pump body assembly, and the conduit is a flexible hose or tube capable of channeling fuel from the pump assembly to the external fuel tank. The conduit and the fuel tank cap assembly comprises mating couplers having valves biased closed when disconnected from the mating coupler. In use, the fuel tank cap assembly is threaded to the external fuel tank, and the conduit coupler is connected to the cap coupler, thus forming a fluid-tight connection between the conduit and the fuel tank cap assembly. Thereafter, the external fuel tank may be replenished by manipulating the pump assembly. In other embodiments, the portable fuel dispensing system has a dual line conduit permitting vapor in the external fuel tank to be evacuated via a vapor line in the conduit and collected in the reservoir of the portable fuel container. In another embodiment, the pump assembly further comprises release valves disposed in the pump body assembly to alleviate pressure differences between the reservoir of the portable fuel container and the external ambient pressure.
