Filter Minder® Fuel Filter Gauge

 

Filter Minder® Fuel Filter Indicator - Tee Fitting

Filter Minder® Fuel Filter Indicator - Straight Fitting

How It Works

The Filter Minder® Fuel Filter Gauge monitors the suction side fuel filter on diesel engines. The yellow position indicator progressively fills the window as fuel filter restriction increases, locking at the highest restriction.  The fuel filter should be changed when the indicator reaches the red zone.

The Filter Minder® should be reset whenever the service indicator is checked to determine fuel filter restriction or when a new fuel filter is installed. Push the reset button at the end of the service indicator, and the position indicator will return to zero.
