Memories.... These 1928 gravity flow gas pumps were at the Kings Canyon Lodge. The sight brought back memories of my farming childhood in the 1940s. Each morning my dad loaded the 1929 Buick (converted to a truck and a vehicle I eventually learned to drive) with the ten gallon cans of milk and drove the less than a mile to the cheese factory in the nearby village of Morrison.
The cheese factory had a gravity flow gasoline pump. Dad didn't purchase gasoline there since there were fifty gallon drums at the farm for gasoline which was delivered by a local farmers co-op. I do remember asking what those pumps were as someone was filling a container from the pump. Memories of the gasoline disappearing from the glass container atop the pump was intriguing to this five or six year old mind. Most likely I asked how the gasoline got there. Just as likely there was an answer. However, I have no recollection of that.
At the Kings Canyon Lodge, the gasoline storage tanks were on a nearby hillside so the glass globes atop the gasoline pumps were filled with gravity, just as those globes were drained by gravity.
