I have a UA 50 on the front of my 59 international. I know of a guy with a 46 dodge fire truck and though it leaks from every seal it still pumps water. He uses it at a local steam show every year. I have not put water in my pump but the impeller was stuck, a little PB blaster and some motor oil and a few days later and a couple of taps and it was turning freely. Unless they are rusted completely they may well work great without a rebuild. I have to find a clean pond and operating instructions before I try to pump it. Bill
