I wonder if in the mind of the designer was the thought that a gauge face with the word fuel could also be utilized in the manufacture of the gauge package for trucks that utilized Diesel as the fuel. Kind of falls in line with John's view on cost saving ideas. Being a 1950 Truck, would it be possible that the Korean War, and potential shortages of materials could have impacted a design decision? Obviously we may never know but its been a very interesting post.
