WARNING: Do not smoke or carry lighted tobacco or open flame of any type when
working on or near any fuel- related components. Highly flammable mixtures are always present
and may be ignited, resulting in possible personal injury.
WARNING: Fuel in the fuel system remains under high pressure even when the engine is
not running. Before servicing or disconnecting any of the fuel lines or fuel system components,
the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing
personal injury or a fire hazard.
1. Relieve the fuel system pressure. For additional information, refer to Pressure Relief in this
section.
2. Remove the fuel tube clip.

Vapor Tube
Disconnect
1. WARNING: The evaporative emission system contains fuel vapor and condensed
fuel vapor. Although not present in large quantities, it still presents the danger of
explosion or fire. Disconnect the battery ground cable from the battery to minimize the
possibility of an electrical spark occurring, possibly causing a fire or explosion if fuel
vapor or fuel liquid is present in the area.
Disconnect the battery ground cable.
2. Disconnect the vapor tube from the fitting. 1. Squeeze the fitting.
2. Disconnect the vapor tube from the fitting.
Connect 1. Clean and inspect the fitting and the tube for damage.
2. Push the tube into the fitting until it snaps in place.
3. Pull on the connection to make sure the fitting is secure.

DESCRIPTION AND OPERATION
Fuel Tank And Lines
WARNING: Do not smoke, carry lighted tobacco or 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, possibly resulting in personal injury.
The vehicle utilizes a returnless fuel system consisting of:
zthe fuel tank.
z a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped
into the fuel tank.
z a 1/8 turn fuel tank filler cap.
z a fuel filter providing filtration to protect the fuel injectors.
z a single fuel line accommodating the returnless fuel system.
z a fuel injection supply manifold which contains a differential pressure sensor and a fuel
temperature sensor.
z a fuel pump and sender assembly which provides pressurized fuel to the engine and contains:
„an inlet filter.
„ a check valve which maintains system pressure after the pump is shut off.
„ a pressure relief valve for overpressure protection in the event of restricted flow.
The fuel pump is controlled by an electronic fuel pump driver module which is enabled by the
powertrain control module (PCM). Electrical power to the fuel pump is provided through the inertia fuel
shutoff (IFS) switch, which is located in the luggage compartment. SECTION 310-
