[AT] Mystery port on Super M water pump

[Brian]

Probably an after market water pump made  for several different 
applications.  On the SM would have a plug in it.  On a combine maybe 
plumbed for a heater.  This farmer maybe decided he needed a tank heater 
in the winter and decided to plumb it there.
