Replacing the propane tank on your gas grill is really easy and doesn't take long at all once you're familiar with all of the grill parts. Most tanks are connected to the grill with a line that connects to the burners. You'll know when you need to replace your tank when your grill won't ignite anymore. As you switch out the propane tank, make sure you look for any broken or damaged parts, particularly the gas regulator and fuel hose. If you notice any issues, order replacement grill parts to keep your grill operating safely.
