listed in the service schedule. Section 1 shows the
typical location of a fuel filter.
procedure below to replace the fuel filter.
Fuel Filter Cleaning/Replacement Procedure
1. Close the fuel supply valve.
2. Loosen the fuel filter by turning it counterclockwise.
Remove the fuel filter and use rags to clean up
spilled fuel oil. Dispose of the fuel filter in an
approved manner.
3. Clean the contact surface of the fuel oil filter
adapter.
4. Lightly lubricate the gasket surface of the new fuel
filter with fresh fuel oil. Thread the filter on the
adapter
until
the
hand-tighten the filter an additional one-half turn.
Wash hands after any contact with fuel oil.
5. Open the fuel supply valve.

when fuel (free of water) flows from the fuel/water
separator.
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
flows free of air bubbles).
13. Replace the air bleed screw.
