I would suggest donating that to the Smithsonian, and purchasing a pump made in this millennium.
I have been through Shurflow, Jabscos, Marco gear pumps, and FloJet. I had a problem wherein after the leave the boat, the pump loses its prime, and runs without pumping. I would then have to run the faucets to get air out. You would think I had a leak, but not so. I just this spring bought a Johnson 5.0GPM variable Flow Master#: 10-13329-104, And it so far has worked impeccably, and all my previous problems have gone away.
