The fuel pumps in nearly all modern cars are located inside the fuel tank. there's a host of reasons why this is a good idea, one of them being the reliability increase of the electric pump when it's located there.
Because the pumps is actually inside the tank, not attached to the outside, or inline to the engine, the electric motor is submerged in fuel. That means the pump motor is being cooled by the fuel, effectively negating the major cause of electric motor failure, heat.

This is actually a myth. The fuel pump is not cooled by the fuel on the outside, only the fuel running through it. So as long as you have any fuel at all, the pump is not going to overheat. And once you actually run out of fuel the pump will shut off, so basically you cannot overheat your fuel pump.
