How does a fuel pump operate?
The basic way your modern electrical fuel pump works is by utilizing a DC motor in the pump assembly which draws in the fuel sitting in your gas tank. From there, it sends it up the fuel line and into the fuel rail where it can be injected into a cylinder. It then mixes with air and a spark to create combustion.

How does a mechanical fuel pump work?

Do electric fuel pumps get weak?
Because fuel pumps constantly run whenever the ignition is turned on, they can eventually wear out and weaken over time. A weak fuel pump may still pump fuel, but the vehicle may experience difficulty starting from the lack of pressure.
Why do electric fuel pumps fail?
The top reasons for fuel pump failure are contamination, overheating, and the gears in the the fuel pump wearing out over time. By running on a low gas tank, the fuel in the gas tank heats up a lot quicker causing the fuel pump to overheat or even worse, run dry.

Why is fuel pump in tank?
The higher pressure raises the boiling point of the gasoline. Placing the pump in the tank puts the component least likely to handle gasoline vapor well (the pump itself) farthest from the engine, submersed in cool liquid.
