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 power switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work.
