The fuel storage system (1) has a main tank (2) and an auxiliary tank (3), where the main tank and the auxiliary tank are connected with an internal combustion engine (9) through a valve device. The internal combustion engine is connected with the main tank through a return line (13). A two by two-way valve (7,8) is provided in a connecting line of the valve device between the respective tanks and the internal combustion engine. Each tank has a level sensor (4,5), where the measured values are supplied to a central evaluation unit (6). The central evaluation unit controls a level indicator and the two by two-way valve. An independent claim is included for a method for controlling the fuel storage system. Die Erfindung betrifft ein Kraftstoffspeichersystem (6) mit einem Haupttank (2) und wenigstens einem Zusatztank (3). Der Haupttank (2) und der Zusatztank (3) sind jeweils über ein 2/2-Wege-Ventil (7, 8) mit einem Verbrennungsmotor (9) verbunden. Nicht verbrauchter Kraftstoff gelangt über eine Rücklaufleitung (13) zurück zum Haupttank (3). Verfahrensgemäß werden die wenigstens zwei 2/2-Wege-Ventile (7, 8) über eine entsprechende Logik angesteuert, sodass in Abhängigkeit der Füllmengen zwischen dem Haupttank (2) und dem Zusatztank (3) hin- und hergeschaltet wird.
