Fuel/Water Separator's Element Replacement

Procedure

At the interval specified in the service schedule, replace

the fuel/water separator element.

1. Close the fuel valve at the nearest point to the water

filter inlet or at the fuel tank.

2. Remove the water drain plug (or push up the drain

valve) and allow water and fuel to flow into a

suitable container.

Note: Depending upon the location of the fuel valve, a

considerable amount of fuel may drain out.

3. Remove the separator's element from the mounting

head by twisting in a counterclockwise direction.

4. Remove the bowl from the fuel/water separator

element. Wipe the excess fuel from the bowl and

the O-ring. Do not discard the bowl or O-ring.

5. Inspect the components for wear or damage.

Replace parts as necessary.

6. Lubricate the O-ring with clean diesel fuel and

replace it in the bowl.

7. Install the bowl onto a new fuel/water separator

filter element.

8. Lubricate the bowl/element assembly with clean

fuel.

Install the bowl/element onto the filter

mounting head.

9. Replace the water drain plug (if removed) and

close the vent.

10. Remove the air bleed screw from the fuel/water

separator.

11. Open the fuel supply valve.

12. After fuel fills the water separator, allow fuel to flow

from the air bleed hole until all air is displaced (fuel
