Abstract

To provide a fuel supply system for an engine that can enhance the assembling workability even though each fuel injector has an attaching angle different from one another,fuel injectors 57-60 are divided into a plurality of injector groups including a first injector group 65 and a second injector group 66. A first fuel supply rail 72 is connected to the fuel injectors 57, 58 of the first injector group 65, and the second fuel supply rail 73 is connected to the fuel injectors 59, 60 of the second injector group 66. The first fuel supply rail 72 and the second fuel supply rail 73 are connected to each other through a connecting unit 75.
