WARNING!
Do not smoke, carry lighted tobacco or have 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. Failure to follow these
instructions may result in serious personal injury or death.
Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when
working on or near any fuel-related component. Highly flammable mixtures are always present and may be
ignited. Failure to follow these instructions may result in serious personal injury or death.
When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage.
Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instruc-
tions may result in serious personal injury or death.
NOTE :
Make sure not to spill fuel inside of the vehicle. 8. Tip the fuel pump on its side and drain the fuel from the fuel pump and remove the fuel pump from the vehicle. NOTE: To keep the fuel tank portion clean and to avoid damage and foreign materials, cover them completely
with plastic bags or something similar.
9. Remove and discard the seal from the fuel tank.
10. Installation is in the reverse order of removal.
Installation Notes:
• Install a new seal to the fuel pump sealing surface.
• Turn the ignition switch to ON (without starting the engine) to apply fuel pressure to the fuel system, then
check the connections for fuel leaks.
• Start the engine and let it idle and check for fuel leaks at the fuel system connections.

Description
The fuel filter consists of a housing with an integrated filter element.
Operation
The fuel flows through the filter from the outside to the inside. As a result, any impurities are trapped inside the filter.

Fuel Injector
Description
The fuel injectors are positioned in the intake manifold with the nozzle ends directly above the intake valve port.
Operation
Injector operation is controlled by a ground path provided for each injector by the Engine Control Module (ECM).
Injector on-time (pulse-width) is variable, and is determined by the ECM. Based on the engine operating conditions,
the ECM will control injector pulse-width operation to obtain optimum performance.

Description
The fuel pressure regulator is connected to the fuel rail. The fuel pressure regulator has a vacuum connection to it.
The fuel pressure regulator is used to regulate the fuel pressure in the fuel system.
NOTE :
The 2.4L is the ONLY engine that uses an external fuel pressure regulator.
Operation
The fuel pressure regulator is designed to keep the fuel pressure in the fuel system at a constant pressure. It does
this with a spring-loaded diaphragm that controls a valve. The valve, when opened by excessive pressure in the fuel
lines, uncovers a fuel line that returns excess fuel to the fuel tank. The vacuum connection is there to help reduce
emissions during deceleration. During deceleration, the vacuum connection serves to open the fuel return valve
wider, which reduces pressure in the system and prevents excess hydrocarbon emissions due to less fuel being
injected as a result of the lower pressure in the system.
Removal & Installation
WARNING!
Release fuel system pressure before servicing fuel system components. Service vehicles in well ventilated areas
and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.
1. Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
