Could you blow yourself up this way?

Liquid fuel is difficult to ignite as long as everything stays submerged there is no chance it would ignite and explode. If you have any fuel in the tank, the vapor concentration is far past what you can ignite. (gasoline doesn't burn at all. gasoline vapors burn, and it has to be between 1 and 7% vapor to air. Any more or less and it won't do a thing) The only time you would get that low of a concentration of vapor in the tank is if it is absolutely empty, in which case you aren't moving the sender anyway.
