Abstract: A unitary fuel system module comprising one or more fuel cylinders mounted to a frame as a module, preferably through neck-mounts, and having fueling lines for connecting the fuel cylinders to the vehicle. The frame is fitted with a latching mechanism that is readily actuated for alternately securing the frame to the fuel supply envelope in the vehicle or releasing the frame for removal of the fuel module as a unitary structure. Preferably, the frame is fitted with wheels or slides to enable sliding the module in and out of the envelope. In operation, as required return a vehicle to operation, a faulty module can be replaced with a replacement module, which is slid into the envelope where it is secured and the fueling lines are re-connected to the vehicle.
