Fuel System Maintenance

Pressure Regulator
The pressure regulator components have been specifically
designed and calibrated to meet the fuel system
requirements of the engine.
If the regulator fails to operate or develops a leak, it should
be repaired or replaced with the OEM recommended
replacement parts. When inspecting the regulator, check the
following:
• Check for any fuel leaks at the inlet and outlet fittings.
• Check for any fuel leaks in the regulator body.
• Check to ensure the regulator is securely mounted and
the mounting bolts are tight.
• Check the regulator for external damage.
Mixer/Throttle Control Device
The mixer and throttle body components have been
specifically designed and calibrated to met the fuel system
requirements of the engine.
Note that a dirty air filter may significantly alter the mixer
performance. Ensure the air filter is clean.
When inspecting the mixer and throttle body, check the
following:
• Check for leaks at all fittings.
• Ensure the mixer and throttle body are securely
mounted.
• Inspect and clean the air filter element according
to the recommended service intervals listed in the
maintenance chart.
• Inspect air inlet hose connection and clamp. Inspect
hose for cracking, splitting, or chafing. Replace as
necessary.
• Check fuel lines for cracking, splitting, or chafing.
Replace as necessary.
• Check for leaks at the throttle body and intake
manifold.

Exhaust System Maintenance

When inspecting the exhaust system, check the following:
• Inspect exhaust manifold at the cylinder head for leaks.
• Check that all retaining bolts and shields (if used) are in
place.
• Inspect fasteners between the manifold and exhaust
pipe to ensure they are tight and there are no exhaust
leaks. Repair as necessary.
• Inspect the oxygen sensor electrical connector to
ensure it is seated and locked. Check wires to ensure
there is no cracking, splitting, chafing, or burning.
Repair or replace as necessary.
• Inspect exhaust pipe connection for leaks. Repair as
necessary.

Storage

The standby generator system is designed for long term
service. There is no need to take storage precautions.
However, should it become necessary to take the system out
of service for an extended period, call Technical Services at
800 732-2989 between 8:00 AM and 5:00 PM central time
