If you are going to have a museum to cars, why not include a tribute to the thing that makes them go? While fuel itself is not terribly suitable for an exhibit, the pumps that provide it prove to be a surprisingly good idea. Blackhawk Automotive Museum has a bunch of different gas pumps from through the years on display. They are all restored to pristine condition and probably look far better than they did when they were new.
The pumps cover a number of years and a variety of gas companies. The evolution of the pump designs is quite clear as you go through the years. I am not sure I fully understand how they worked but they seem to have involved filling up a clear vessel at the top of the pump with fuel. This filling process allowed you to work out exactly how much fuel was to be provided. Then, when the amount was worked out, the hose would allow you to drain the fuel down to the vehicle.
The early versions seem to be quite simple in layout and, as the years pass, the systems seem to become a bit more complex. A modern pump is way more complex but also severely lacking when it comes to styling. These old pumps look like they had some artists involved in styling them and the colors of the companies were similarly intricate. I guess that is how things worked in those days. Now efficiency, maintainability and functionality will win out over style.
