I have a Bayou Classic KAB4 burner, and a few extra 100 pound propane tanks. I have copper tubing and different flare fittings. Has anyone rigged up a big propane tank to run their burners? I'm not sure the best way to attach the tank to the regulator. My first thought was to cut the rubber tubing, use a barb fitting and a hose clamp to attach the copper tube to the regulator, but I worry about that leaking.
