I believe that the Camp Chef hoses contain a regulator at the bottle end, and they screw into the stove directly, replacing the rigid section of pipe that the 1lb bottles attach to (I believe that that piece of piping contains a built in regulator, which is why there hose/regulator bypasses it.
I have this hose
5ft Propane Hose Assembly from Mr Heater that I use with my Buddy Heater and cookstove to run them off a 20lb tank. It has a standard tank connection on one end, and the other end has a connection that matches the 1lb bottles, just screws it into where the 1lb bottle goes on your stove. This hose does not include any regulator and will supply high pressure from the bottle to the appliance, so you will need to retain the 1lb bottle connection on the stove as you do not want to have unregulated fuel supply to the stove. The hose should work with any portable propane appliance that uses the 1lb bottles. The hose is available in 5, 10, and 12 foot lengths.
I like it as there is no mods needed, just screw it in place of the 1lb bottle and go, then I can keep a spare 1lb bottle hidden away in case the big tank runs dry half way through dinner due to lack of planning..lol
