Hey everyone! I was wondering do electric fuel pumps wear out faster when they are not inside the gas tank? I was wondering this because to me it doesn't make sense how something electric can be submerged in a liquid without shorting out.
because gasoline is an insulator. It also helps cool and lubricate the pump.
In fact, oil is used to insulate high voltage transformers.
how something electric can be submerged in a liquid
Most liquids actually do not conduct electricity (except maybe mercury)
Water doesn't conduct electricity either. The impurities in it do.
Watch some Youtube videos.

Fuel pumps are lubricated by the gasoline that they pump, that's why, if you run out of gas, don't keep trying to start it, you'll burn the pump out. Oh the days when there weren't electric fuel pumps, 18 months ago, the fuel pump went out in my '79 Catalina and there were only two bolts that needed to come out. The engine directly powers the fuel pump via the camshaft in that car.

It's actually not the water itself that shorts things out. Distilled water doesn't conduct electricity, we did an experiment 15 years ago in Chemistry class in high school proving this. Water only conducts electricity because of the molecules dissolved in the water. Sodium chloride dissolved in water conducts electricity, for example.
