This is an example of a visible pump that was built in 1924.  These pumps first appeared around 1915.  Gasoline was pumped from underground tanks into a visible glass cylinder above the pump.  The operator watched the level of gas in the cylinder and stopped the flow when the gas reached the desired amount.
You don't need no stinkin gas.  EV4U can help.
