    Very well machined, went right on. Much better than the junk plastic stock cap.

    Looks Great

    This cap along with the oil filter cap look awesome. My only complaint is that the nut on top of fuel bowl is not a 26mm but a 25 mm. So my snap-on flip socket for the 6.0 filters won't work. Not sure if this is a defect in the build of what.

    What a heavy duty product. Easy install, amazing looking! Got this and the oil lid as well. Looks great and won't crack like the plastic one.

    I love these Billet caps, they fit great and do not leak.
    the 6.0 cap has a -3 opening (That is a dash 3) a 3/16" ORB Male (3/8"-24 thread) . I found some on a Hydraulic Hose website
