fuel sender question

I wonder how many safety freaks would crap their pants if they knew that there was an uninsulated wire with electricity flowing through it inside their gas tanks! :cheers:

In theory it is impossible to blow up a fuel tank in this way. ANY amount of gasoline in the tank will evaporate to it's natural state of vapor pressure, and in a very short time, will create such a saturated over-rich mixture that it can not possibly burn.

There IS an "envelope" of combustible mixture. In the same way that a fuel cannot burn "too lean" it cannot burn "too rich," either.

My first real heavy electric fuel pump back in the '70's was a Carter motor drive. The motor in this pump operates submerged in fuel. Of course nowadays this is commonplace
