In automotive, industrial, and power generation applications, the water-in-fuel sensor is integrated into the fuel filter. It is automatically replaced whenever the fuel filter is replaced. For marine applications the sensor is not integrated into the fuel filter and is a serviceable item.
Possible causes:
1)Water in fuel
2)Damaged sensor
3)Fuel contamination.
Possible repairs:
1)Flush the dirt, debris, or moisture from the connector pins.
2)Replace the water-in-fuel sensor.
