Dave,
I still suspect that you have an air bubble in the pump. If so, it *will
not* pump or self prime based on my tests when I was measuring the flow. I
had to get the pump under water to get it to pump, then it was like a
firehose.

Thanks Kelly,

About 2 weeks ago I spent an entire day taking off my water pump just so
that I could check for such an error.  I inspected it very carefully,
the two are indeed separate.  But thanks for the input.  Keep em coming.
