In-tank fuel pump module used for fuel injection systems on many different vehicles (both gasoline and diesel) consists of the fuel pump, fuel pressure mechanical regulator, fuel filter, fuel level sensor all enclosed in one unit with pipes, flanges and electrical connectors. Also fuel temperature sensor, fuel tank pressure sensor and some other electrical and mechanical parts could be integrated into in-tank fuel pump module. An idea behind integrating multiple parts into single components is to accommodate easier, better and quicker assembly and therefore lower cost of the vehicle.
