The fuel filter for diesel engine plays an important role of separating water from fuel and accumulating it on the bottom. If water is accumulated in the fuel filter when the ignition switch is in the ON position, the warning light will be turned ON.
If water accumulated in the fuel filter is not drained timely, damages to the major parts such as the fuel system can occur due to water permeation in the fuel filter.
Place a water trap under the fuel filter.
Remove the fuel filter assembly.
(Refer to Fuel Delivery System - " Fuel Filter")

After draining water, securely tighten the water sensor.
After starting the engine, make sure that the fuel filter warning light is turned OFF.
