A fuel-conveying system includes: a primary fuel pump, configured to supply fuel to an internal combustion engine of a vehicle, at a fuel pressure; a suction jet pump configured to convey fuel from a first region of a fuel tank of the vehicle to a second region of the fuel tank, the at least one suction jet pump having a nozzle; and a secondary fuel pump, decoupled from the primary fuel pump and configured to: supply, as required, the suction jet pump with a fuel jet, and set, independently of the primary fuel pump, a pressure of the fuel jet before the nozzle of the suction jet pump.
