Abstract
A system, for preventing overflow in a tank, fillable via a nozzle, includes a fill passage connecting the storage tank to an external atmosphere. An adjacent passage has a lower end disposed at a predetermined level within the storage tank and an upper end communicating with a hole in the fill passage. A vent passage connects the adjacent passage to the external atmosphere, and a valve is disposed in the vent passage, permitting the flow of air through the vent passage and prohibiting the flow of liquid through the vent passage.
