Fuel Heater: Description and Operation
DESCRIPTION AND OPERATIONFuel Filter/Fuel Heater/Water Separator Assembly:
This engine is equipped with a fuel filter/fuel heater/water separator assembly. A WATER IN FUEL indicator lamp is provided on the instrument panel to alert the operator. The lamp should glow when the ignition switch is in the ON position to indicate proper lamp and water sensor function. If the lamp glows continuously while the engine is running, the water must be drained from the fuel filter/fuel heater/water separator manual drain valve as soon as practical to prevent damage to the fuel injection system.
