Yep that helped answering all the questions.
I was wondering if the gas company would have the fittings needed maybe even the needle valve but I guess looking around E bay & the internet will help to get a better price than the gas company. Probably would not hurt since they could provide the fittings & I could check out their needle valves for info anyway. I am sure their prices would be higher.
I will check out your threads on CO2 to further educate myself on the solenoids & regulators. Thanks Anthony for your time spent. You have been very helpful. Roger
