Never run out of fuel again with the Cuisinart In-Line Propane Tank Gauge. 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. And you’ll know when it’s time to refill by the indicator on the dial of the tank gauge. You’ll be able to constantly monitor the propane level of your 20lb propane tank. Just attach the hose to one end of the tank gauge while the gauge is connected to the propane tank. No tools required for this easy hookup and looking at the dial is all you need to do to know the status of the remaining propane.
