CAUTION:

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.

Note:

This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.
