    • An injection system for an internal combustion engine has a prefeed pump for delivering fuel from a fuel tank, a high pressure pump for delivering the fuel to a fuel accumulator arranged downstream of the prefeed pump, an accumulator return line arranged downstream of the fuel accumulator and used to return the fuel from the fuel accumulator to the fuel tank, and a valve arranged in the accumulator return line and by which the fuel can be optionally supplied to the fuel tank or to a tank bypass line which hydraulically leads to a point between the prefeed pump and the high pressure pump. A pressure relief valve is arranged in the accumulator return line downstream of the valve and upstream of the fuel tank. The pressure relief valve is suitably designed to allow adjustment of a fuel pressure in the accumulator return line upstream of the pressure relief valve.
