Automotive in-tank fuel pumps use gasoline for lubricant. At least it
sure looked that way when I disassembled one. Even more exciting, the
brushes/commutator area is flooded with fuel. Apparently not a problem
even when you run out of fuel and start sucking air.
I also always wondered about the fuel level sensor, like a big wirewound
potentiometer up in the air area of the tank.
It appears to be quite safe.
But I would certainly want a second opinion before implementing my own
version!
Cheerful regards,
Bob
