Interesting fact: Built in 1898, one of the first gas pumps could pull fuel from an underground tank. It features a glass cylinder on top of the pump where you could see whether the gas you’re getting was dirty or not.
It also has a manual pump to help pull the gas out of the underground tank into the cylinder, and finally into the hose leading to the car.
