They had a hand operated pump that one used to pump the gasoline up into
the glass cylinder at the top. You filled the cylinder to the number of
gallons you wanted to purchase, then placed the hose nozzle into the gas
tank opening. Pulling the lever on the nozzle allowed the gasoline to
flow by gravity feed into the gas tank.
When I worked as a firefighter for the U.S. Forest Service at the Big
Dalton Canyon Station in the Angeles National Forest circa 1957 we used
one of these hand operated gas pumps to fill our trucks. The idea was a
good one. We could always pump gas even when the electricity failed.

Subject: Antique Gas Pump Question
I'm looking a picture of a gas pump from the 1920's. It has a globe at
the
top of it and a set of numbers inside of the globe. Does anyone know how
these "antique" gas pumps worked?
