PURPOSE: To cover insufficient capacity of mechanical fuel pump by providing a fuel path for feeding the fuel delivered from a motor fuel pump directly to a delivery pipe without pressurizing through a mechanical fuel pump while providing a check valve in the fuel path.
CONSTITUTION: Fuel is fed from a fuel tank 1 through a motor fuel pump 8 to a mechanical fuel pump 7. Said pump 7 will feed the fuel through a delivery pipe 4 to an internal-combustion engine 2. Prior to start or under low rotation of engine, the delivery of mechanical fuel pump 7 is lower than that of motor fuel pump 8, thereby the pressure P0 in the fuel pipings 9, 10 will increase and push open a check valve 11 upon exceeding over the pressure P1 in the delivery pipe 4 thus to feed the fuel to the delivery pipe 4.
