GENERAL INFORMATION
DThe steel fuel tank is located under the floor of the rear seats to provide increased safety and increase
the amount of luggage compartment space.
DThe 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.
DThe fuel pump module contains a fuel pump, fuel filter, and fuel pressure regulator.
