Abstract: A fueling system for a vehicle equipped with an engine fueled by compressed gas and a storage system for storing the gas under pressure and providing the gas to the engine, includes a compressor on board the vehicle for receiving gas at a first pressure through an inlet and outputting the gas a second pressure higher than the first pressure through an outlet, an electric motor connectable to an electric power source outside the vehicle for powering the compressor, a low-pressure connection for removably connecting the inlet to a source of low-pressure gas at the first pressure, and a high-pressure connection between the outlet and the fuel storage system. The compressor preferably compresses in two to four stages. The fueling system permits an operator to recharge the fuel cylinders of a gas-powered vehicle from a source of low pressure gas, such as a metered residential gas line, using standard AC line power and simple gas fittings.
