ABSTRACT:
A fuel overflow alarm system sounds a buzzer or other alarm when a fuel level in a fuel tank of a vehicle or other machine approaches an overflow state, thereby alerting a user that fueling should be halted. The device is activated when a fuel cap or fuel cap cover on a filler inlet tube to the fuel tank is opened and is de-activated when the filler inlet tube is closed. Thus, electrical current drawn by the system can be limited to time periods when the fuel tank is being filled, thereby sparing the electrical system of the vehicle or machine from being depleted during periods of non-use.
