So, If the tank is almost empty and the cap is off, or ventilated there must be a stage where the fuel/air ratio would support combustion, in which case any bad connection to the pump or fuel gauge could set it off.

1379697 2014-07-27 22:15:00 yes there is a stage where air/ful ratio is close enough. guys have been killed when welding tanks.
but bad connections causing a spark big enough to ignite it.......extremely remote. voltage is to low and allowable current is fairly low to.
theres a much bigger risk of rubber hose splitting leaking fuel and catching fire.
