CAUTION: During all repair procedures on the fuel tank, be aware of the following:
- Make sure that the Ground (GND) (-) strap between the fuel filler tube and body is securely fastened, to prevent electrostatic charging.
- Route all the various lines (e.g. for fuel, EVAP system, or vacuum) and electrical wiring so that the original routing positions are restored.
- Ensure sufficient clearance to all moving or hot components.
