All you need is one of these fittings you can connect between one of your cylinders and the pigtail, and then connect a long hose to your grill. We just remove the pigtail from the cylinder and connect a hose from there to the grill. We also carry a one gallon refillable cylinder that we can use if we set up the grill farther away from the rig than the hose will reach.
