CAUTION:


  • B004CJ8

    Never perform work on fuel system components near any possible ignition sources.

  • Vaporized fuel could ignite, resulting in a serious accident.


  • B004AP0

    Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.

  • Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

PROCEDURE


  1. PRECAUTION

    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.
