Fuel System Maintenance
This Operator’s Manual contains more detailed fuel and fuel system maintenance
information than the engine Owner’s Manual, which is a general-purpose reference relating
to fuel and fuel maintenance.
Ensure that you understand that the fuel system maintenance, fuel storage, and fuel quality
require your attention to avoid downtime and extensive engine repairs.
The fuel system has extremely tight tolerances due to the emissions and control
requirements. Diesel fuel quality and cleanliness is more important for the longevity of
today’s high-pressure common rail (HPCR) fuel-injection system used on diesel engines.
IMPORTANT
Water or air in the fuel system will damage your engine! Do not assume that new fuel
is clean. Ensure that your fuel is from a quality supplier, store your fuel correctly, and
use your fuel supply within 180 days.
IMPORTANT
If you do not follow the procedures for fuel filter replacement, fuel system
maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform
all fuel system maintenance at the specified intervals or whenever the fuel is
contaminated or its quality is poor.
Fuel Storage
Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks
is often overlooked and leads to the contamination of fuel delivered to the machine.
• Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has
been stored for more than 180 days. This helps eliminate water and other contaminates
in the fuel.
• If you do not remove the water from the storage tank or machine fuel tank, it can lead to
rust or contamination in the storage tank and fuel system components. Tank sludge
developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel
injectors.
• Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality
in the tank.
• Ensure that your fuel comes from a quality supplier.
• If you find water or contaminants in your storage tank or machine fuel tank, work with
your fuel provider to correct the problem and perform all fuel system maintenance.
• Do not store diesel fuel in tanks or canisters made with zinc-plated components.
