FUEL SYSTEM PRECAUTION


  1. BEFORE WORKING ON FUEL SYSTEM


    1. Before inspecting and repairing the fuel system, disconnect the cable from the negative (-) battery terminal.

      Note

      After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work Click here.

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

    3. Keep fuel away from rubber or leather parts.

  2. 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.

        Note


        • Be sure to disconnect the fuel tube connector by hand.


        • Do not scratch or allow any foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the pipe (fuel pipe).


        • Do not bend, twist, pinch or kink the nylon tube.

      6. Check that there is no foreign matter on the sealing surfaces of the disconnected fuel lines. Clean them if necessary.

      7. Cover the disconnected fuel pipe and fuel tube connector with plastic bags to prevent damage and contamination.

    3. Quick Type A:

      Perform the following procedure when connecting a fuel tube connector.

      Note

      Check that there is no damage or foreign matter on the connecting parts of the fuel lines.


      1. Align the fuel tube connector with the fuel pipe, and push them together until the fuel tube connector makes a "click" sound. If it is difficult to push the fuel pipe into the fuel tube connector, apply a small amount of clean engine oil to the tip of the fuel pipe and reinsert it.
