IMPORTANT: This service should be performed by
an Authorized PCM Premier dealer.
CAUTION
Refer to FLUSHING COOLING SYSTEM before
proceeding.
1. Fill the fuel tanks with gasoline and add a
suffi cient amount of gasoline stabilizer, such
as STA-BIL™ fuel stabilizer, to prevent the
formation of fuel gum and varnish. Follow the
instructions on the container.
WARNING
On fuel injected engines, you MUST bleed off fuel
pressure before proceeding. Failure to do so
may cause personal injury.
2. Remove, empty and clean the fuel fi lter
assembly. Reinstall with a new fuel fi lter and
gasket / seals. Refer to Engine Maintenance for
fi lter replacement procedures.
NOTE: DO NOT re-use old fuel fi lter components.
Always replace with new fuel fi lter element and gasket /
seals.
WARNING
Accumulation of water and other fuel
contaminants may form corrosive compounds
that can damage the fuel fi lter, and result in fuel
leakage. Ethanol blended fuel may increase this
risk. For this reason, annual replacement of the
fuel fi lter, at a minimum, is required to avoid risk
of explosion or fi re.
WARNING
Operate the bilge blower and be sure no fuel vapors
are present when treating the engine. Be sure the
engine compartment is well-ventilated to prevent a
potential fi re hazard.

operating temperature (a minimum of 10
minutes). Shut down the engine and change the
oil and oil fi lter (See ENGINE MAINTENANCE).
