The Overfill Alert Gauge is a high level visual gauge designed to visually alert you that your AST (tank) is near full. This overfill monitor's simple pop up mechanical design promotes easy installs, maximum durability, and low up front costs.
Also, by purchasing our Overfill Alarm Accessory, you can turn your visual overfill gauge into an audible overfill alarm.
