I do not know of a governor but I know of a generator. I think you have the wrong G word. LOL.... Meaning the tube that changes the liquid into a vapor.
I have never had to change one. There are You Tube video's of guys doing some however I tried this on the Coleman site.
I have a Dual Fuel Coleman but if you select which one you have it shows the part breakdown and the generator.
Coleman - Repair Parts: Dual Fuel
Once you know the part number, then you can search the web or buy from Coleman. Amazon came up with several just I do not know if they fit yours.
Good luck and hope this helps
