Abstract: My invention relates to an emergency air jump system for use with motor vehicles having an internal combustion engine that is started by an air type starter. This type of engine is usually started, when on the road, by means of air from an air tank charged from an air compressor actuated by the engine when running. When the air from the tank is depleted a stopped engine cannot be started without outside air. My air jump system provides a means of recharging or re-pressurizing the air tank by utilizing the existing air from a tire normally used or carried by the vehicle, thereby obviating the need for road service. The jump start air line has a coupling adapted to be sealingly connected to the existing outside accessible coupling to the air starter tank, an air line connected to the jump coupling at one end and connected to a female air chuck at the other end.
