OPERATION - 2.5L
The fuel injector rail supplies the necessary fuel to
each individual fuel injector.
The fuel damper is used only to help control fuel
pressure pulsations. These pulsations are the result
of the firing of the fuel injectors. It is not used as a
fuel pressure regulator. The fuel pressure regulator is
not mounted to the fuel rail on any engine. It is
located on the fuel tank mounted fuel pump module.
Refer to Fuel Filter/Fuel Pressure Regulator in this
group for information.
The fuel rail is not repairable.
REMOVAL - 2.5L
The fuel damper is not serviced separately.
WARNING: THE FUEL SYSTEM IS UNDER CON-
STANT FUEL PRESSURE EVEN WITH ENGINE OFF.
THIS PRESSURE MUST BE RELEASED BEFORE
SERVICING FUEL RAIL.
(1) Remove fuel tank filler tube cap.
(2) Perform Fuel System Pressure Release Proce-
dure as described in this Group.
(3) Disconnect negative battery cable from battery.
(4) Remove air tube at top of throttle body. Note:
Some engine/vehicles may require removal of air
cleaner ducts at throttle body.

ing cylinder (Fig. 20). If not, identify each connector
before removal.
