Removal

Warning:

Do not smoke, carry lighted tobacco or an open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited, possibly resulting in personal injury.

Fuel supply lines on all vehicles equipped with fuel injected engines will remain pressurized for long periods of time after engine shutdown. Fuel system pressure must be relieved prior to fuel system service to prevent possible personal injury or a fire hazard.

1. Disconnect the battery.
2. Relieve the fuel system pressure.
3. Drain the fuel tank.
