The Venturi effect, as gasoline passes by the bleeder poppet it creates a pressure delta. This delta causes air to rush into the gasoline. This is why if you see gasoline being dispensed it is aerated, not just a steady flow of gasoline. This Venturi effect creates a vacuum in the nozzle to keep the valve open for fuel dispensing
but why does the air flow through tube?
