CAUTION!
During all repair procedures on the fuel tank, be aware of the following:

• Make sure that the ground (-) strap between the fuel filler tube and body is securely fastened, to prevent electrostatic charging.

• Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.
