Abstract
A compressed natural gas fuel tank for vehicles employing internal combustion engines. A fuel tank of heavy gauge metal is interposed within the vehicle frame as an integral portion thereof. Overlay channel members are welded or otherwise affixed to the tank and then welded or otherwise affixed to the side rails or channel members of the vehicle frame. The tank, of heavy gauge metal and non-circular cross section, is also welded or otherwise appropriately affixed to the vehicle floor. The tank is capable of receiving natural gas at high pressure levels, while also serving structurally as a frame element, providing continuity of the side rail members of the frame, while also serving to further interconnect the vehicle floor with the side rails.
