I got a reply. They suggest getting the Badger filter/regulator and guage made by them. I took the suggestion and ordered that and an airbrush holder from Dixie. Figured that if I kitted myself with Badger, might as well use what they designed for their equipment. Thanks for all the help.
I do think that the regulator I got was not fine enough in its ability to handle low flows.
These forums are great for this stuff!!!!
