Tour the Demoiselle
Fuel Tank
This is a picture of the gas tank for the Demoiselle. It
didn't hold very much fuel, but you weren't planning on flying very
far. They were very small tanks. The copper line that's coming down
from the front of the tank is the fuel line. That curled look to it
is not just for Jules Verne style or anything. That is actually very
practical and very useful. And that was used to dissipate the
vibration from the engine so that the fuel line wouldn't crack. And
by curling it like that, you added a lot more life to the fuel line.
