In a fuel feed apparatus comprising a fuel pump 5, a strainer 6 and a pressure regulator 7, said fuel pump 5 and at least either of said strainer 6 and said pressure regulator 7 being arranged in a fuel tank, a holder 9 is arranged at an upper portion of reservoir 4b mounted in said fuel tank in order to hold the fuel pump 5 and the strainer 6 or the pressure regulator 7. The fuel pump 5 and the strainer 6 or the pressure regulator 7 are connected by a coupling cover 11 so that they may be held in position by the holder 9 and the coupling cover 11. The coupling cover 11 contains a check valve 20 in it. A thermistor 24 is arranged within the fuel tank 2 in order to detect the volume of fuel left in the fuel tank 2. The thermistor 24 is held within the fuel tank 2 by a thermistor arm 26 made of an electrically conductive material. The thermistor arm 26 is connected to the strainer 6 at an end thereof and to the grounding terminal of the thermistor 24 at the other end thereof where an earth-connecting section 26a is arranged. Thus, the thermistor arm 26 operates also as the grounding terminal of the strainer 6 so that the thermistor 24 and the strainer 6 share a common grounding terminal. <IMAGE>
