No. The fuel vapors in a tank are so ridiculously "rich" that is far past the ignition envelope. The AF envelope for various fuels goes "so far" lean and "so far" rich. Outside of those ratios, fuel could never ever ignite.
Look at "in tank" pumps. These use FAR more power than your fuel sender uses, and the brushes!!! which spark!!! run right in!!! the fuel!!!
