Accel pump diaphragm source?

Hope someone here recognizes this and can help me find a diaphragm.

This accelerator pump was mounted between float bowls number two and three in an aftermarket sort of fashion. It feeds tubes that go up to holes that have been drilled and tapped on the intakes of the carburetors for nozzles. The carb set in question resembles a VM29 in every way except for the bowls, which do not have the jet-access-plugs.
 

Thanks for any help. So good to see KZrider is still around!

I have one.  Normally reserved for people buying an O-ring kit, but I'll make an exception.  Send a PM if interested.

The Kawasaki part# for the diaphragm used on the 650 and 1000 bikes is  43028-1012. I found several locations that sell kits which included this item. with a simple search. Now I do not know if the pump you have is the same as those used on the bikes mentioned.

I know that Mikuni sold kits for pumps on 29s  see attached and it looks much like those on other carbs (vm24ss vm26ss and vm28ss)


But you make is sound like your system looks more like this (this is a set of vm28sc carbs with a pump).


As long as the diaphragm is the same size the part number posted above should work
