This is a new reproduction 12 volt fuel gauge. This is for the MB, GPW, CJ2A, and CJ3B. It will also work with the M38 and M38A1 if you are not using the 24V system. This requires a 2″ hole to fit. (standard gauge hole in the jeeps listed) This has a black bezel and real glass. If you want a green bezel you will have to paint it. There is no back lighting just like the originals in the MB, GPW, CJ2A, and CJ3A.
