ABSTRACT:
A fuel routing structure for use in a vehicle having a V-type engine is provided. The structure has fewer parts, is compact, and facilitates ease of assembly and maintenance for a vehicle where fuel injection valves are attached to an intake manifold, which contains an intake passage communicating with intake ports of a pair of cylinder banks. Each fuel injection valve is attached to an upper part of the intake manifold, so that center lines of the fuel injection valves corresponding to both banks are crossed at an intersection over the intake manifold when a vehicle is viewed from the side. A fuel rail is provided with a fuel passage pipe, the axis of which is arranged in the vicinity of the intersection of the center lines of the fuel injection valves. The axis of the fuel passage pipe may be parallel to the crankshaft and may extend linearly and connected to all the fuel injection valves.
