Fuel/Water Separator: Description and Operation
DESCRIPTIONThe design of the fuel manager/filter includes an area that allows water droplets (as small as one micron) to separate from the fuel and collect in a lower portion of the housing. The water in fuel sensor will detect a certain amount of water in the fuel inside of the filter housing and then turn the Water the Fuel lamp ON in the instrument cluster. When the ignition switch is first turned to the run position, the Water in Fuel lamp will come ON for 2 to 5 seconds. This action provides a bulb check.
