ABSTRACT:
An automatic fuel shutoff system for preventing fuel flow into a tank being filled when the level of fuel in the tank reaches a predetermined level. This system stops fuel flow when the passage of light from a light transmitter to a light receiver is blocked by the presence of fuel in a detector gap formed near the outlet of a fuel-dispensing nozzle.
