7.1.2 Generator Fuel Filter / Water Separator
The generator fuel filter/water separator is located on the forward engine room
bulkhead ( Figure 7-1 ). The filter element should be changed either every 400
engine hours; at every generator oil change; or annually, whichever comes first.
Refer to the generator user manual for additional information.
Check the sediment bowl periodically and drain if water is present. Water and
contaminates settle to the bottom of the bowl.
To drain water from the generator fuel filter/water separator:
1. Ensure all engines are OFF.
2. Remove the drain plug on the bottom.
3. Drain the bowl into a proper receptacle and discard according to local laws
and regulations. (Drain one cup of fuel and check for consistency in color;
if water is visible, drain out more fuel until clean fuel is present).
4. Reprime the unit by following the generator priming instructions below.
To prime the generator:
1. Ensure all engines are OFF.
2. Spin the filter element/bowl assembly off the mounting head and fill with
clean fuel.
3. Spin the filter element/bowl assembly back onto the mounting head and
tighten snugly by hand only —do not use tools.
4. Verify all other connections are tight.
5. Start the generator and check for fuel system leaks.
6. Correct as necessary with all engines off.
To change the generator fuel filter element:
1. Turn OFF generator fuel valves ( Figure 7-1 ). See chapter 3 for valve loca -
tion.
2. Remove the drain plug on the bottom.
3. Remove the filter element/bowl assembly from the head/mounting bracket.
