Abstract
An assembly for a fuel injection system for use with an internal combustion engine, comprises a fuel injection system component and a plurality of injectors mounted on the component. The component comprises a plurality of air passages for supplying air into the engine, a plurality of injector seats and a fuel passage communicating with the injector seats. Each injector has a vapor discharge passage communicating with the inside of the injector and with the fuel passage, and/or has a filter inserted in the fuel passage so that fuel vapor in the injector is smoothly discharged from the injector into the fuel passage, thereby preventing vapor lock of the injector system. The component may be directly mounted to a surge tank so that an independent intake manifold need not be used.
