FUEL INJECTOR AND FUEL TUBE

5. Disconnect fuel injector harness connectors.
6. Disconnect EVAP canister purge control solenoid valve.
7. Disconnect fuel hose assembly from fuel tube (RH bank and LH bank).

CAUTION:

• While hoses are disconnected, plug them to prevent fuel from draining.

• Do not separate fuel connector and fuel hose.

8. Remove fuel injectors with fuel tube assembly.
9. Remove fuel injector from fuel tube.
a. Spread open to remove clip.
b. Remove fuel injector from the fuel tube by pulling straight out.

CAUTION:

• Be careful with remaining fuel that may leak out from fuel

tube.

• Do not damage injector nozzles during removal.

• Do not bump or drop fuel injectors.

• Do not disassemble fuel injectors.

10. Remove fuel damper from each fuel tube.

INSTALLATION

1. Install fuel damper to each fuel tube.
a. Apply engine oil to O-ring and set it into the fuel tube.

CAUTION:

• Handle O-ring with bare hands. Do not wear gloves.

• Do not reuse O-ring.

• Lubricate O-ring with new engine oil.

• Do not clean O-ring with solvent.

• Make sure that O-ring and its mating part are free of for-

eign material.

• When installing O-ring, be careful not to scratch it. 

• Also be careful not to twist or stretch O-ring.

• If O-ring was stretched while it was being attached, allow

it to regain it’s shape before inserting into fuel tube.

• Insert O-ring straight into fuel tube. Do not angle or twist it.

b. Make sure that backup spacer is in the O-ring connecting surface of fuel damper.

NOTE:

Backup spacer is fuel damper assembly part.

c.

Insert fuel damper until it seats on fuel tube.

CAUTION:

• Insert straight, making sure that the axis is lined up.

• Do not pressure-fit with excessive force.

d. Install cap, and then tighten bolts evenly by turns.

• After tightening bolts, make sure that there is no gap between cap and fuel tube.

2. Install O-rings to fuel injector paying attention to the items below.

CAUTION:

• Upper and lower O-ring are different. 

• Handle O-ring with bare hands. Do not wear gloves.

• Do not reuse O-rings.

• Lubricate O-ring with new engine oil.

• Do not clean O-ring with solvent.

• Make sure that O-ring and its mating part are free of foreign material.

• When installing O-ring, be careful not to scratch it. 

• Also be careful not to twist or stretch O-ring.

• If O-ring was stretched while it was being attached, allow it to regain it’s shape before inserting

into fuel tube.

• Insert O-ring straight into fuel tube. Do not angle or twist it.

3. Install fuel injector to fuel tube.
a. Insert clip into clip mounting groove on fuel injector.

• Insert clip so that lug (A) of fuel injector matches notch (A) of

the clip.

CAUTION:

• Do not reuse clip. Replace it with a new one.

• Be careful to keep clip from interfering with O-ring. If

interference occurs, replace O-ring.

b. Insert fuel injector into fuel tube with clip attached.

• Insert it while matching it to the axial center.

• Insert fuel injector so that lug (B) of fuel tube matches notch

(B) of the clip.

• Make sure that fuel tube flange is securely fixed in flange fixing

groove on clip.

c. Make sure that installation is complete by checking that fuel

injector does not rotate or come off.

• Make sure that protrusions of fuel injectors are aligned with

cutouts of clips after installation.

4. Install fuel tube and fuel injector assembly to intake manifold.

CAUTION:

Be careful not to let tip of injector nozzle come in contact with other parts.

• Tighten fuel tube assembly bolts “a” to “b” in illustration and in

two steps.

5. Install fuel hose assembly.

FUEL INJECTOR AND FUEL TUBE

Do not reuse O-ring.

• Follow precautions for fuel injector when handling O-ring.

• Insert connectors straight, making sure that the axis is lined up with fuel tube side to prevent O-ring from

being damaged.

• Tighten bolts evenly in several steps.

• Make sure that there is no gap between flange and fuel tube after tightening bolts.

6. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

After installing fuel tubes, make sure there are no fuel leaks at connections using the following steps.
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel

leaks at connections.

2. Start the engine and rev it up and check for fuel leaks at connections.

WARNING:

Do not touch the engine immediately after stopping, as engine becomes extremely hot.

NOTE:
