It is a device to draw fuel from a fuel tank and to deliver it to injectors.In the early stages of electronic fuel injection systems, fuel pumps were out-of tank, in-line type which installed outside of the fuel tank. From about 40 years ago in-tank type pump which installed inside of the tank became the mainstream.

Currently module type that integrates not only a pump but also a fuel flow rate detection device as a potentiometer or a float arm, a fuel filter and even a pressure regulator that regulates the fuel pressure is the mainstream.
