ABSTRACT:
The present invention relates to a fuel injector post for connecting a fuel injector to a fuel rail. The fuel injector post comprises a tubular body portion with a central axis having a circumferential wall, an open end and an outlet on the tubular body portion. The fuel injector post further comprises an adapter portion positioned at an angle to the central axis of the tubular body and integral with the outlet on the tubular body portion. The adapter portion has a passage in fluid communication with the tubular body portion and the fuel rail and therefore connects a fuel injector to the side of a fuel rail, which is advantageous to the engine package. Alternatively, the tubular body portion can have a closed end configured and adapted to reduce air entrapment in the tubular body portion to therefore reduce or eliminate pressure waves in the entire fuel system due to entrapped air.
