Hi Dave, try Zimmerman - https://www.crawlerbulldozer.com. If you find one, have it sent to me and I'll bring it over at Xmas which will save a bit of shipping. Might not be much for such a small item anyway
No luck with Zimmerman or Cat. Still looking for options if anyone has one please.
Cheers
Dave
Another option is to fit a generic valve and bowl. All you need to do is adapt a unit from a Ferguson or similar generic. That will get you up and running. Cat does have new remote fuel shutoffs for over by the pinion controls so you can get one of those if your tractor has that feature. I put one on my tractor before I found a good used Zenith that I was able to clean up
