Thank you for looking, Billy.


Commonly referred to as 252A5891, 252B2891, 252 and 252A generators. These are original military surplus generators. If you have a United States issued military surplus generator that takes the "hooked" generator this is the one you will need.
Do not forget to remove the bottom screw and top fuel jet protector prior to installation, see photos.
