Some cars use plastic gasoline tanks, why do not produce static fire?
In addition, about liquid conductivity. Think of the transformer, which is full of transformer oil. Transformer oil has a much higher insulation strength than air.
It's true that gasoline will rub out static electricity in a plastic bucket. You go to the gas station with a plastic pot and the gas station won't sell you any oil. The car's tank is metal, and electrostatic charges do not accumulate.
The inner part of the plastic gasoline tank is coated with a conductive layer for grounding, which can not cause static electricity.
