[Spridgets] Air pump ports

[John Caffrey]

   Hi Bud,
   Not  important enough to argue about since both size plugs will do the
   job,  but  I did have challenge for those who would insist that 1/8-27
   NPT is the correct thread. Screw the air injection manifold into a 1/8
   pipe coupling and remove it undamaged, and I buy the beer! I wonder if
   Larry  would  share the Guiness with me?  Samuel Adams Lager is brewed
   in my hometown now, and it would be a fine choice also.

   The idea of 7/16-20 came from measuring the mating air manifold. It is
   a  7/16-20  UNFstraight  thread,  it is not a tapered pipe thread. 1/8
   pipe  is  a  bit  smaller and the pitch is close so a 1/8-27 pipe plug
   screws in, that doesn't make it the thread size.
