Description of the Related Art A fuel supply device is known which comprises a plurality of electric fuel pumps and drives the fuel pumps at the same time to supply the fuel discharged from the fuel pumps to a fuel injection valve ( See JP-A-4-159448). In this fuel supply device, each fuel pump is driven by distributing the drive current generated by the current generation circuit to each fuel pump. Therefore, for example, when the current supply conductor to any one of the fuel pumps is disconnected and the supply of the drive current to this fuel pump is stopped, the drive current to be originally supplied to this fuel pump is distributed to the remaining fuel pumps. Therefore, the drive current supplied to the remaining fuel pumps is increased. As a result, the amount of fuel discharged from the remaining fuel pumps increases, so that even if one of the fuel pumps stops, the same amount of fuel as before the stop of this fuel pump can be supplied to the fuel injection valve.

料量が大巾に減少してしまうという問題を生ずる。However, in this fuel supply system, when the fuel pump is stopped due to a mechanical cause such as seizure, the electric resistance of the stopped fuel pump is extremely lowered, and therefore the current generating circuit is used. Most of the generated drive current flows through the stopped fuel pump. As a result, the drive current supplied to the remaining fuel pumps is greatly reduced, so that the amount of fuel to be supplied to the fuel injection valve is significantly reduced.

The fuel is supplied to the second fuel pump 10 because the pressure difference between the absolute pressure in the surge tank 4 and the fuel pressure in the fuel distribution pipe 7 must be maintained at the set pressure only by the fuel discharged from the fuel pump 10.
