Specifications

Use a clean, good quality No. 1-D or No. 2-D diesel fuel
oil with a cetane number of 45 or greater. The fuel must
meet the requirements of the American Society of
Testing and Materials (ASTM) diesel fuel classification
D975.
Use clean fuel since diesel engines have easily clogged,
precision fuel injectors and pumps.
Recommended fuel:
United States ASTM/D975-66T, No. 1-D or No. 2-D
diesel oil.
United Kingdom BS2869 Class A1.
Never store diesel fuel in galvanized containers; diesel
fuel and the galvanized coating react chemically to
produce flaking which quickly clogs filters or causes fuel
pump or injector failure.
Do not run the generator set out of fuel since the fuel
lines will draw in air and necessitate bleeding the fuel
system before restarting the unit.
Avoid storing fuel for more than one month. Take special
precautions to keep all dirt, water, and other
contaminants out of the fuel. Diesel fuel storage tanks
containing contaminants and water may cause the
growth of microbes. Microbes form slime which clogs
the fuel filter and lines.

2. Loosen the fuel filter by turning it counterclockwise.
Remove fuel filter and use rags to clean up spilled
fuel oil. Dispose of fuel filter in a safe and approved
manner. See Figure 3-6.

3. Clean contact surface on fuel oil filter adapter.
4. Lightly lubricate the gasket surface of the new fuel
filter with fresh fuel oil. Thread filter on adapter until
