Water In Fuel Indicator: Description and Operation

1985 Models W/Diesel Engine, Exc. Chevette & 1000
The Water In Fuel warning system employs a fuel detector integral with the fuel filter and fuel heater, and mounted on the engine. When more than 2.2 ounces of water has been collected in the filter, the Water In Fuel lamp on the instrument panel will light. After the light comes on, the filter should be drained as soon as possible to prevent fuel injection system failure or damage.
