As mentioned above the 1lbs. Bottles just don’t have enough “ umf “ for the Blackstone and the OE regulators gives you options. I use a 5lbs. tank ( I have hardware in my back ) because it’s easy to move around and a 8 foot hose. I would think you could get the OE regulator from Blackstone or Amazon. Keeping things simple makes for better camping IMHO. Good luck and have fun camping!
