Abstract: A fuel delivery system for an internal combustion engine, the system comprising at least one fuel injector, said fuel injector comprising a control chamber having an inlet for receiving highly pressurised fuel and an outlet enabling fuel to flow out of the control chamber into a back-leak passage associated with the fuel injector, wherein the fuel injector is operable between an injecting state and a non-injecting state in dependence on the fuel pressure within the control chamber. The system further includes a pressure regulator for regulating the fuel pressure within the back-leak passage so as to maintain the injector back-leak pressure at a predetermined target value which is below atmospheric pressure.
