ABSTRACT:
An integrated fuel system for use in an internal combustion engine has a fuel meter body including a first, upper housing and a second, lower housing which are joined along a sealing flange to define a fuel plenum therebetween. The upper and the lower housings each have fuel injector sockets in opposed pairs; each injector socket in the upper housing opposing a corresponding socket in the lower housing. The sockets open through the respective housing walls and are configured to reversibly capture a fuel injector between each pair. The reversible mounting of the injectors within the fuel plenum facilitate fuel delivery from two sides of the fuel meter body to thereby simplify fuel distribution in a small fuel intake. A novel mounting configuration for the fuel meter body within the intake manifold is also disclosed.
