ンプ制御装置。 A fuel supply system that supplies fuel to the engine from one chamber of a saddle-shaped fuel tank with a bifurcated bottom by a fuel pump, and a fuel return system that returns excess fuel from the engine to one chamber of the fuel tank as return fuel. a fuel transfer system that transfers fuel from the other chamber to one chamber of the fuel tank using a jet pump provided in the fuel return system; and a constant flow rate of return fuel returned to the fuel tank by the fuel return system. 1. A fuel pump control device for an engine, comprising: fuel pump control means for increasing the amount of fuel supplied to the engine by the fuel pump of the fuel supply system when the amount of fuel supplied to the engine by the fuel pump of the fuel supply system decreases below the amount of fuel supplied to the engine.
