A steel plug with a 1/8" Allen hex head, used for draining the oil rail before pulling injectors. Genuine Navistar OEM parts.

    I had two oil plugs strip out when I tried to remove the old ones in my Ford 7.3 diesel. I bought all four new ones and they worked PERFECTLY! THANK YOU RIFFRAFF!

    If you ever remove the originals do not put them back in, use these instead, at the very least replace the orings. This product comes with quality orings.

    These tend to strip. Had to replace injector O rings.So for the price purchased these just in case.
