WARNING:

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

Vaporized fuel could ignite, resulting in a serious accident.

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.

The fuel tank sub-assembly is very heavy. Be sure to follow the procedure described in the repair information, or the fuel tank sub-assembly may fall off the engine lifter.

NOTE:

After the ignition switch is turned off, the radio and display receiver assembly or the radio receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
