7. Pull the fuel pump up and out of the fuel tank.

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.

Fuel Pump Inspection

1. Using the following table, apply battery voltage to the specified connector terminals.

2. Check the fuel pump resistance.

• Take out the fuel pump.

• Connect the digital multimeter to terminals 2 and 3. Check the fuel pump resistance.

• If the result is not as specified, replace the fuel pump.

3. Check fuel pump operation.

• Remove the fuel pump.

• Apply battery voltage to terminals 2 and 3. Check that the pump operates within 10 seconds.

• If the pump does not operate, replace the fuel pump.

NOTE:

• These tests must be completed within 10 seconds to prevent the coil from burning out.

• Keep the fuel pump as far away from the battery as possible.

• Always switch the voltage on and off on the battery side, not on the fuel pump side.

Fuel Filter

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.

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).

2. Disconnect the negative battery cable.

3. Remove the fuel delivery hose (1), fuel outlet hose

(2) and the ground wire (3).

4. Remove the fuel filter.

5. Installation is in the reverse order of removal.

Installation Notes:
• Verify there are no leaks at the fuel line connec-

tions of the fuel filter.

Fuel Injector Rail

Description

The fuel rail is used to mount the fuel injectors to the engine and it is mounted to the intake manifold.

Operation

The fuel rail supplies the necessary fuel to each individual fuel injector and is located above the intake manifold and
fuel injectors.

Removal & Installation - 1.6L & 1.8L & 2.0L

WARNING!

1. Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).

4. Disconnect the electrical connectors (1) from the

fuel injectors.

5. Remove the fuel line (2) from the fuel rail.

6. Remove the two fuel rail (4) bracket bolts (3) that

mount the fuel rail to the intake manifold.
(Tighten: Fuel rail bracket bolts to 11 N·m)

7. Remove the fuel rail with the four fuel injectors (1).

8. Installation is in the reverse order of removal.

Installation Notes:
