  I have a 33 model 40 how does the gas gauge work?

  Very slight air pressure is developed in the gas tank sending unit. The pressure travels through a very small tube to the back of the dash gauge. The pressure displaces a red fluid to the front glass tube. More pressure the higher the red fluid less pressure the lower the red fluid.

  Thanks does the ignition have to be on for the system to work?

  No, it's basically a mechanical gauge.

For some reason the first page is on the RIGHT, the second page is on the LEFT:
