A fuel injector pump in a direct-injection fuel delivery system for an internal combustion engine including a solenoid valve for controlling the transfer of fluid from the high pressure chamber of the camshaft driven pump pressure chamber to a fuel injector nozzle. A supply passage accommodates fuel delivery and return for fuel supplied by a fuel pump. A second independent leak flow path is provided to accommodate fuel leaking past a plunger of the high pressure pump, the fuel leak path extending to the fuel supply rather than leaking past the high pressure plunger of the pump to the engine lubrication oil circuit.
