GENERAL INFORMATION

The steel fuel tank is located under the floor of the rear seats to provide increased safety and increase

the amount of luggage compartment space.

The fuel tank has been equipped with a valve assembly which incorporates a fuel cut-off valve to

prevent fuel from leaking out in the event of a collision for adjusting the pressure inside the fuel

tank.

The fuel pump module contains a fuel pump, fuel filter, and fuel pressure regulator.
