Abstract
A fuel feed unit for a motor vehicle, having a pressure-limiting valve arranged in a working fluid line of a suction jet pump which is arranged within a surge chamber of a fuel tank. Excess fuel therefore passes directly into the surge chamber via an outlet of the pressure-limiting valve. Unnecessary circulating of the fuel in the fuel tank is therefore avoided.
