What Is It And How Does It Work
What Is It

This is a tank level indicator. This indicator should me mounted within site of the fill tube.
One per tank or optional selector switch to transfer from tank to tank.

This is the sensor. One of these units per tank to be monitored.
How Does It Work
The indicator lights up or an optional audible alarm will sound to alarm you a tank is full,
so that there is no over spill.

Push the indicator in to make sure the light and optional audible alarm works.

As the tank fills up, notice the indicator in the back is not on because the fuel has not filled the tank yet.

Tank is now full, notice the indicator light is on and there was no spills.

The tank is not pressed totally full and leaves room for expansion. This level is repeatable everytime!!
