The fuel quantity measuring system on that 100 model did not have intrinsically safe barriers. It was built in 1971.
Nonsense. I encountered those barriers in the 1960s. I bet the aerospace industry was an early adopter.
By the way, there isn’t much oxygen in a fuel tank. Rarely enough to support combustion inside the tank.

Every car built since the mid 1990’s has an electric fuel pump sitting in the bottom of the tank with 12vdc and a 20-30 amp fuse going to it. Often there are cracks in the insulation or sometimes chunks missing yet how many car fires do we see that begin in the tank?
Gasoline is a lot more volatile than Jet-A.
