[Spridgets] Air pump ports

John, Larry,
I stand corrected (and slightly embarrassed).  I was just SURE that.
Getting old really sucks, sometimes :-)

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.
