Abstract
A injection conversion body with internal injector compartment for converting a normally carbureted internal combustion engine to a fuel injected engine while concealing the fuel delivery system. The original engine carburetor is removed. The plenum assembly is mated to the original engine intake manifold and a suitable throttle body is mated to the intake apertures which are oriented to permit installation without modification to the vehicle body work or relocation of other engine components. Air drawn through the throttle body is mixed with fuel from fuel injectors inside the plenum as it is directed to and exits the fuel air exhaust opening and enters the engine intake manifold. Interchangeable restriction plates are provided for insertion into the plenum fuel air exhaust opening to tune the fuel/air mixing characteristics to match the needs of the engine with which it is mated. Fuel is delivered to the fuel injectors through an internal, concealed fuel rail and fuel lines.
