The Air Eject is a simple, air operated, pneumatic connector, which 
permits connecting an air pressure line to a vehicle. When the engine is
 cranked, the Air Eject automatically disconnects the air line, thus 
preventing the vehicle from being driven away with the line connected. A
 solenoid valve wired to the vehicle's starter is energized when the 
engine is started. This provides air pressure to a cylinder, which 
extends to release the air line. The Air Eject is supplied with the 
mating air line connector, and check valve. Installation and wiring on 
the vehicle are simple, and easily accomplished.
