The real gauge to watch is the pressure gauge. The car's tank fills to 3600 PSI, so the pump shuts down once it reaches that pressure. Only takes a minute or so.

Then you turn off the nozzle and make sure the pump is off, and the pump vents the small amount of pressurized gas that was in the hose up this pipe and right into the atmosphere.

The whole process of filling the tank make sounds that are similar to filling your tires with air, except without all the leaking air noises. The nozzle seal is air tight to 3600 PSI.
