A dual fuel system includes a plurality of fuel injectors that each have a non-injection configuration, a liquid fuel injection configuration, a gaseous fuel injection configuration and a combined fuel injection configuration. Each of the fuel injectors includes a liquid control valve member with a guide segment that defines a portion of a leak path from a liquid fuel inlet to a drain outlet, and a gas control valve member with a guide segment that defines a second leak path from the liquid fuel inlet to the drain outlet. Each injector body includes a tip component that defines both a liquid nozzle outlet set and a gas nozzle outlet set. A dual solenoid actuator has a first armature coupled to the liquid control valve member, a second armature coupled to the gas control valve member, and a shared stator.
