Default Trash pump diaphragm source?

Hello, all. Saved a net little trash pump with a Clinton B700 on it the other day. There are no markings on the unit that I can find. Sits on a little 2 wheel rolling truck. I'll see about getting some photos later.
The working end of the pump is about 16" square, with about a 14" round diaphragm inside. It's not just flat rubber, it's bowled of course. Again, I'll see about photos. Of course, it has been covered in dirt for many years open to the elements and the rubber is shot. Has about a 5" stroke so I really doubt something like an inner tube would hold up even for show purposes.
Anyway, did some searching but mostly found piston pump info. What are you fellow mud sucker pump owners doing?

I, too am looking for a replacement diaphram for a Goulds mudsucker. Local dealer is not interested in getting one for us, says no profit in it The pump ws made in the '30s, and was used in a local mine for many years. The mine was abandonned in 1958, and the pum was recovered via scuba gear in the late 1960s. Our engine club has had it since. Anybody have diaphrams for our old pumps?

Here's a google hit - they say that they have various rubber coated fabrics for diaphraghms. Might not hurt to give them a call...

Always try McMaster-Carr for odd stuff.
