Fuel pump question

Frank, I'm sure you'll find the problem here, but my guess it that the pump
has a diaphragm problem.  This is rare as they are a really tough material.
It could be that it is partially stuck or gummed up and not getting it's
full travel, resulting in partial pumping.  Fully primed, it works; any air
at all and it won't pump.  I had this happen to one of mine.   Just taking
it apart and cleaning it up should restore it.
