A method and structure are described for preventing the accidental introduction of an incorrect liquid into a tank, such as the introduction of gasoline into the fuel system of a diesel-powered vehicle. In a first embodiment, the entrance to a fill tube of a diesel-powered vehicle is configured with a sensor ring. When an incorrect fueling operation is attempted, such as the introduction of gasoline into the fuel tank of a diesel-powered vehicle, at least one but fewer than all of displaceable mechanical elements are displaced, and the sensor ring alerts the operator visually and/or audibly before fueling starts, thereby preventing incorrect fueling.
