Fuel injector adapter

A method of assembling an internal combustion engine, comprising:

• providing a fuel injector disposed in a rocker base on the internal combustion engine;
• attaching an adapter shaft of a fuel injector adapter to the fuel injector, the adapter shaft including a first shaft end disposed within the fuel injector, a second shaft end, a shaft passage disposed in the adapter shaft extending from the first shaft end to a port portion of the adapter shaft;
• disposing a fitting portion of an adapter body about the adapter shaft, the adapter body including the fitting portion with a first end and a second end, a bore including a fuel portion, an elbow port including a port fuel portion;
• and an extension connecting the fitting portion to the elbow port including a fuel passage connecting the port fuel portion of the elbow port to the fuel portion of the bore proximate the port portion of the adapter shaft;
• connecting an elbow to the adapter body, the elbow including an elbow body with a connector end disposed within the elbow port of the adapter body and a bulkhead end attached to a bulkhead on the rocker base.

An internal combustion engine, comprising:

• a rocker base;
• a fuel injector attached to the rocker base;
• a fuel injector adapter connected to the fuel injector, further comprising:
• an adapter shaft including a first shaft end disposed within the fuel injector, a second shaft end, a shaft passage disposed in the adapter shaft extending from the first shaft end to a port portion of the adapter shaft, the port portion including annular openings, and
• an adapter body disposed over the adapter shaft, including a fitting portion including a first end, a second end, and a bore including a fuel portion and a monitoring portion, an elbow port spaced from the fitting portion, the elbow port including a port fuel portion and a port monitoring portion, and an extension connecting the fitting portion to the elbow port, the extension including a fuel passage connecting the port fuel portion of the elbow port to the fuel portion of the bore proximate the annular openings of the port portion of the adapter shaft, and the extension including a monitoring passage connecting the port monitoring portion of the elbow port to the monitoring portion of the bore, and
• an elbow connecting the fuel injector to the rocker base.
