Never run out of fuel again with the Cuisinart in-line propane tank gauge. Don't put expensive food at risk of under cooking because you've run out of fuel. The Cuisinart in-line propane tank gauge makes it easier than ever to manage your fuel so you won't run out when you least expect it. Once you attach the gauge to your tank, you won't have to take it off again until it's time to refill the tank. No tools are required for this quick and easy hookup. Simply attach one end to the 20-lb. propane tank and the other end to the grill hose. The large face is easy to read with a yellow indicator showing when fuel is running low and red when it's time to refill.
