Removal

WARNING:
- When working on or near the evaporative emission (EVAP) system, disconnect the battery ground cable from the battery. The EVAP system contains fuel vapor and condensed fuel vapor, so an electrical spark may cause a fire or explosion. Failure to follow this instruction may result in serious personal injury.
- Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

NOTE: Some vehicles come equipped with a steel fuel tank that is mounted midship. This fuel tank is referred to as an auxiliary fuel tank.

All vehicles
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Disconnect the battery ground cable.
