WARNING: Always disconnect the battery ground cable at the battery when working on an evaporative emission (EVAP) system or
fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in
serious personal injury.
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component.
Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent
accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this
instruction may result in serious personal injury.
WARNING: Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any
fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in
serious personal injury.
WARNING: When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage. Spilled fuel may be
ignited by hot vehicle components or other ignition sources. Failure to follow these instructions may result in serious personal injury.
NOTICE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is essential that absolute cleanliness is
observed when working with these components or component damage may occur. Always install plugs to any open orifices or tubes.
NOTICE: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector
retaining clip area before separating from the tube or damage to the tube or connector retaining clip may occur. Apply clean engine oil to the
end of the tube before inserting the tube into the connector.
NOTE: During the repair or replacement of fuel-related components, all fuel liquid and fuel vapor openings must be capped, taped or otherwise
appropriately protected to prevent the ingress of dirt or other contamination. All caps, tape and other protective materials must be removed prior to
installation.
