A common rail for an accumulation type fuel injection system is formed of a plurality of pipe connectors in the form of a cross or a tee and a connecting pipe for connecting the pipe connectors with each other. Respective ends of the pipe connector provide pipe connecting portions, to which a pump pipe and injector pipes are connected, and another pipe connecting portion, to which the connecting pipe is connected. Insides of the pipe connectors and the connecting pipe provide a volume portion for accumulating high-pressure fuel. Thus, conventionally required welding technology is not required. Therefore, production cost of the common rail is reduced. Meanwhile, the size of the common rail is reduced and the common rail is mounted to a vehicle more easily.
