A fuel-supply unit for a motor vehicle has a fuel container (2) that has several chambers (6, 7). The unit has a transfer pump (5) that is located inside the fuel container (2) for exclusively supplying ejector pumps (9, 10), which are positioned in the chambers (6, 7), with fuel as the pumping fluid. A primary fuel pump (4) that is located outside the fuel container (2) supplies an internal combustion engine (1) of the motor vehicle with fuel. The transfer pump (5) is operated discontinuously to prevent unnecessary power consumption.
