A fuel supply device includes a fuel pump, a plurality of valves, and a controller. The fuel pump includes a plurality of pressure chambers each having a volume that is expanded and contracted by the engine. The plurality of valves open and close the pressure chambers. An expansion time and a contraction time of the pressure chambers are each different. The fuel pump is operable to sealingly store fuel in the pressure chambers by closing the valves. The controller sets closing times for the valves in accordance with a required quantity of fuel to be force fed. The controller switches between a normal control in which all of the pressure chambers sequentially force feed fuel and a thinned-out control in which the force fed fuel is thinned out by stopping closing at least one of the valves.
