Abstract
A fuel system in which a fuel dispensing nozzle removably and sealably engages a fuel tank. Pressure sensing means in the nozzle monitors the degree of vacuum established adjacent to the nozzle seal, and in response thereto, actuates a vacuum control apparatus. The latter then functions by regulating the volume of vapor flow withdrawn from the fuel tank, to maintain a desired degree of vacuum adjacent to said seal whereby to avoid or minimize the intake of air into the fuel system.
