It unscrews. You need a specially shaped wrench--either the KMO 608 or something more like the later one. The earlier version had a much shorter handle and not sure on angle. Believe the poster who modified a standard open end to make one said handle on his was about 5 inches long, wrench end could be no more than 3/16 thick or more than 3/8 wide and size of hex was 1 7/16. He also mentioned without the angle, the fill plug had to be removed on the OD he was working on.

The later 51 version shown as comparison
