In a fuel feed system for a spark-ignition internal combustion engine, which system has at least a first injection valve, which is arranged in or on a cylinder head and to which fuel is fed under pressure for discharging directly into a combustion chamber of the internal combustion engine, at least one further injection valve is provided in an engine intake passage to discharge, in certain operating ranges of the internal combustion engine, fuel into the intake passage of the internal combustion engine in addition to the discharge of the fuel of the first injection valve into the cylinder, and the first injection valve is designed for fuel injection volume lower than that required for full power operation of the engine.
