DESCRIPTION AND OPERATION
FUEL DELIVERY SYSTEM
The front wheel drive car uses a plastic fuel tank
located rear center of the vehicle.
The in-tank fuel pump module contains the fuel
pump and pressure regulator. The pump is serviced
as part of the fuel pump module. Refer to Fuel Pump
Module.
The fuel delivery system contains a replaceable in-
line filter. The filter attaches to the frame above the
rear of the fuel tank. Refer to the Maintenance
Schedules in the Introduction section of this manual
for recommended fuel filter replacement intervals.
A returnless fuel system is used on all vehicles.
Fuel is returned through the fuel pump module and
back to the fuel tank. A separate fuel return line
from the tank to the engine is no longer used.
Relieve fuel system pressure before servicing fuel
system components. Refer to the Fuel System Pres-
sure Release Procedure and follow all Cautions and
Warnings. Most fuel system components attach to the
fuel lines with quick connect fittings. Refer to Quick
Connect Fittings in this section.
