ABSTRACT:
A robust, combined fuel rail and wiring harness shield assembly, for each bank of cylinders of an IC engine, comprising a rectangular multi-planar plate having an integral longitud-inal mid-rib on one side, longitudinally bored as a fuel distribution manifold to EFI injectors mounted in generally angled bores spaced along the rib. In cross-section the assembly is generally T-shaped, and is preferably constructed of extruded aluminum. Flanking each side of the mid-rib are wings, one of which includes an angled flange. The mid-rib, wing and associated flange form a wiring management channel. The flange is angled down at approximately 135° on the outboard side of the cylinder bank so that it points vertically downwardly. In operation, assembly pairs are connected to a flexible fuel inlet line in series or parallel, with one (series plumbed) or both (in parallel plumbed systems) assembly longitudinal bores having a threaded plug at the distal end.
