Hi,
The pump may need to be rebuilt, but I'd still try the priming of it first. I had the same problem with my hand pump (hadn't used it in many years), and priming it was all it took. Of course, I don't know what it will do the next time I try to use it so I guess I'd better test it.
Anyway, I primed it by removing the hose at the pump end of the line and filled it with water. Then I reconnected the hose to the pump and it worked beautifully.
Regards,
Stan

Fred,
Sounds like it is sucking air. If everything is air tight the pump should prime easily with a few vigorous strokes, but these hand pumps will NOT prime if they are sucking any air at all.
It could be a tiny crack in the diaphragm.
Also, the two check valves have to seat perfectly too to be able to pump enough air out to suck the water up to the pump.
I would take the pump apart, clean it well, then put it all back together and try it. Look very closely at the diaphragm for holes/cracks. If it is at al suspicious, get a rebuild kit and replace the soft parts.
