Never run out of propane again, especially when grilling. Hook up the propane level gauge between the tank and fuel line hose of your grill, patio heater or other appliance. The easy-to-read dial shows good, low and refill levels. The propane level gauge works on grills with an output of up to 80,000 BTUs per hour. Fits all Type-1 connection propane appliances. Gauge face: 1-5/16".
