ABSTRACT:
A gaseous fuel system for a vehicle including an on-board compressor for recharging an associated pressure storage tank. The compressor and tank are mounted on the vehicle as a structural unit whereby the tank shields the compressor and high pressure gas flow circuits therebetween and provides a heat exchanger surface for the compressor. A regulator in series with a supply line of low pressure gas prevents gas flow when the compressor does not operate to maintain a vacuum in an intervening dispensing line. An O.sub.2 sensor disconnects the compressor motor when the percentage of O.sub.2 exceeds a predetermined safe limit. A bypass circuit allows the tank to be filled from a high pressure supply without operation of the compressor.
