Gaseous fuel system for bi-fuel engines

A vehicle having an engine mounted transversely in a forward engine compartment, the engine having intake ports and an intake manifold connected with the intake ports on a forward side of the engine, and a fuel system comprising:

• a pressurized gaseous fuel supply;
• a plurality of gas fuel injectors connected with the fuel supply for receiving pressurized gas from the fuel supply;
• a common injector block receiving the injectors;
• and
• gas distribution lines, each connected with an outlet of one of the injectors and a corresponding one of the intake ports, to conduct gas fuel from the injectors to the intake ports;
• the injectors being operable in timed relation to discharge pressurized fuel from the fuel supply to the distribution lines for delivery to the intake ports, and
• the injectors, the injector block and the pressurized fuel supply being positioned at a distance from the engine intake ports and at a location other than between the engine and a forward portion of the vehicle;
• wherein an adapter plate is mounted between the engine intake ports and the intake manifold on a side of the engine facing said vehicle forward portion, the plate including intake port openings connecting separate intake manifold runners with associated ones of the engine intake ports, and the gas distribution lines connecting with the plate intake port openings at sheltered locations rearward of the manifold.
