In two of your posts you describe air coming out first before low flow of water this leads me to believe the pump is sucking air into the top part where the rubber diaphragm is. If you look real close where the parting plane is and see some corrosion you probably have a leak there. I am assuming it is a Sure Flow pump? If so you can remove the bolts and clean the diaphragm it is probably black anyways and may be torn(if torn you can replace it)and reseal with silicone adhesive along the parting plane.
Yes - air first. It is a Sure Flow pump. I'll check that out.
