ABSTRACT:
A gas cap removal alert system is provided including a gas tank input mounted on a vehicle. The gas tank input includes a pipe with a threaded inner periphery defining an opening with a circular peripheral edge. A gas cap is included for being removably coupled within the gas tank input. A battery is situated within an interior space of the gas cap. Further provided is an indication mechanism mounted on the gas cap and adapted to alert a user upon the receipt of power. A switch is mounted on the gas cap and further electrically connected between the indication mechanism and the battery. During use, the push button switch has a first orientation for allowing the transfer of power to the indication mechanism and a second orientation for precluding the transfer of power to the indication mechanism upon the coupling of the gas cap within the gas tank input.
