Abstract
A fuel supplier for a motor vehicle, having a fuel tank and an internal combustion engine, includes a fuel pump pumping fuel from the fuel tank to the internal combustion engine, a motor driving the fuel pump, and a control unit carrying out feedback control of duty ratio of voltage applied to the motor such that the actual fuel pressure comes close to a target fuel pressure. The control unit increases a low limit value of the duty ratio in accordance with the change of an accelerator open ratio in an opening direction.
