ABSTRACT:
A fuel injection system for an engine has a plurality of bottom-feed type fuel injection valve assemblies. Each of the assemblies has an outer casing and an injector main body which is accommodated in the outer casing and is electrically operated. The outer casing is provided with a fuel inlet and a fuel outlet in communication with each other. A fuel supply pipe is connected to the fuel inlet of the upstreammost fuel injection valve assembly, and a fuel return pipe is connected to the fuel outlet of the downstreammost fuel injection valve assembly. A connection pipe connects the fuel outlet of each fuel injection valve assembly to the fuel inlet of the next fuel injection valve assembly. A wire harness for supplying power to the injector main body extends through a harness member which has a plurality of valve holders formed integrally therewith. Each valve holder is fixed to the upper portion of the outer casing by a fastener.
