release onto fuel tube.
ii. Insert the quick connector release (A) into quick connector (2) until sleeve (B) contacts and goes no further. Hold quick connec-
tor release on that position.

• Do not pull with lateral force applied. O-ring inside quick connector may be damaged.
• Prepare container and cloth beforehand as fuel will leak out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick connector and fuel feed hose (with damper) dur-
ing installati on/removal.
• To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags, etc. (A) or something similar.

10. Loosen bolts in reverse order as shown, and remove fuel tube
and fuel injector assembly.
CAUTION:
Do not tilt fuel tube, or remain ing fuel in pipes may flow out
from pipes.
11. Remove fuel injector from fuel tube as follows:
a. Open and remove clip (1).
b. Remove fuel injector (2) from fuel tube (5) by pulling straight. CAUTION:
• Do not reuse O-rings.
• Be careful with remaining fuel that may go out from fuel
tube.
• Be careful not to damage in jector nozzle during removal.
• Do not bump or drop fuel injector.
• Do not disassemble fuel injector.
12. Remove fuel damper from fuel tube, (if necessary).
INSTALLATION
1. Install fuel damper as follows:
a. Install new O-ring (2) to fuel tube (1) as shown. When handling new O-ring, be careful of the following:
CAUTION:
• Do not reuse O-ring.
• Handle O-ring with bare hands. Do not wear gloves.
• Lubricate O-ring with new engine oil.
• Do not clean O-ring with solvent.
• Check that O-ring and its mating part are free of foreign material.
• When installing O-ring, be car eful not to scratch it with
tool or fingernails. Also be careful not to twist or stretch
O-ring. If O-ring was stretched while it was being
attached, do not insert it quickly into fuel tube.
• Insert new O-ring straight into fuel tube. Do not twist it.
b. Install spacer (3) to fuel damper (4).
c. Insert fuel damper straight into fuel tube. CAUTION:
• Insert straight, checking that the axis is lined up.
• Do not pressure-fit with excessive force.
• Insert fuel damper until (B) is touching (A) of fuel tube.
d. Tighten bolts evenly in turn. • After tightening bolts, check that there is no gap between fuel damper cap (5) and fuel tube.
2. Install new O-rings to fuel injector paying attention to the following. CAUTION:

quickly into fuel tube.
• Insert O-ring straight into fu el injector. Do not twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip (3) into clip groove (F) on fuel injector (5).
• Insert clip so that protrusion (E ) of fuel injector matches cutout
(C) of clip.
CAUTION:
• Do not reuse O-rings.
• Do not reuse clip. Replace it with 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 (1) with clip attached. • Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion (A) of fuel tube matches
cutout (B) of clip.
• Check that fuel tube flange (G) is securely fixed in flange fixing
groove (D) on clip.
c. Check that installation is complete by checking that fuel injector does not rotate or come off.
• Check that protrusions of fuel injectors and fuel tubes 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 bolts in two steps in numerical order as shown.
5. Connect fuel injector harness.
6. Install intake manifold collector. Refer to EM-146, "Removal and Installation"
.
7. Connect quick connector between fuel feed hose and fuel tube connection with the following procedure:
a. Check no foreign substances are deposited in and around fuel tube and quick connector, and no damage on them.Fuel tube side : Black

b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube. • Insert quick connector (1) to fuel tube until top spool (2) is
completely inside quick connector, and 2nd level spool (3)
exposes right below quick connector.
CAUTION:
• Do not reuse O-ring.
• Hold (A) position as shown when inserting fuel tube into quick connector.
• Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
• Insert until you hear a “click” sound and actually feel the engagement.
• To avoid misidentification of enga gement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does
not come out from fuel tube.
e. Install quick connector cap (3) to quick connector.
• Install quick connector cap with arrow (A) on surface facing indirection of quick connector (fuel feed hose side).
CAUTION:
If quick connector cap cannot be installed smoothly, quick
connector may have not been installed correctly. Check
connection again.
f. Secure fuel feed hose to clamp of quick connector cap.
8. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections as follows:
1. Apply fuel pressure to fuel lines by turning i gnition 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 engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
• Perform procedures for “Throttle Valve Closed Position Learning” after finishing repairs. Refer to EC-
682, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-683, "Work Procedure"
