Fumoto Valve

I have a Fumoto Valve. TZ01 and I think I bought it when I had a 250 Cummins engine. Not sure. Anyway I tried to match it thru the Fumoto guide and can't match it to any engine.
If anyone knows what it will fit and would like to have it. I will be happy to send it to you. Doesn't have the gasket with it.
It has never been used.
Thanks
