Looking for a primary CNG regulator. For a Gas Systems Inc, Hille Range stove/oven. I don't suppose the type of stove is the important part, just that the regulator be correct for a CNG cylinder connection. The installation guide on the old stove doesn't give me much information. Looking for a source for the new one, or if anyone has an old one lying in a basement, if you have converted to propane, I'd be happy to pay shipping. I will get a photo later today if that will help to identify. Thanks for the help.
