    2. Do not smoke or work near fire when handling the fuel system.

    3. Keep fuel away from rubber or leather parts.

  3. DISCHARGE FUEL SYSTEM PRESSURE

    CAUTION:


    • Make sure the engine coolant temperature is 60°C (140°F) or less when performing this procedure.

    • Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.

    • Pressure will still remain in the fuel lines even after performing the following procedure. When disconnecting a fuel line, cover it with a piece of cloth to prevent fuel from spraying or coming out.
