Every Type III Volkswagen (squareback or equivalent) for about 12 years (that's a LOT of cars) had a fuel pump which ran immersed in the gasoline. I never knew of any of them blowing up. - GWE

I once found an in-tank fuel pump at the dump. It ran upright, with the inlet at the bottom, the impeller section, and the motor on top. The fuel flowed from the inlet, through the impeller, THROUGH THE MOTOR, and out the end cap of the motor! "Through the motor" means across the brushes. I couldn't believe it. As long as you have gas, it's OK, but if you run out and start sucking air too, ??? There must have been a low-fuel shut-off for the pump.
