The diesel equipped truck has a multifunction filter for solid contaminants and water. The filter is mounted on the front of the dash.
To drain water:
1. Remove the vehicle fuel tank cap.
2. Place a container below the filter drain hose located below the filter.
3. With the engine off open water drain valve 2-3 turns.
4. Start engine — allow it to idle for about 1-2 minutes or until clear fuel is observed.
5. Stop engine and close water drain valve.
6. Install fuel tank cap.
If the “WATER IN FUEL” light comes on again after driving a short distance or the engine runs rough or stalls — a large amount of water has probably been pumped into the fuel tank. The fuel tank should be purged.
