FUEL INJECTOR AND FUEL TUBE
9. Loosen mounting bolts in reverse order as shown in the figure,
and remove fuel tube and fuel injector assembly.
CAUTION:
Never tilt fuel tube, or remaining fuel in pipes may flow out
from pipes.
10. 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:
 Be careful with remaining fuel that may go out from fuel
tube.
 Be careful not to damage injector nozzle during removal.
 Never bump or drop fuel injector.
 Never disassemble fuel injector.
11. Remove fuel damper from fuel tube.
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:
CAUTION:
 Handle O-ring with bare hands. Never wear gloves.
 Lubricate O-ring with new engine oil.
 Never clean O-ring with solvent.
 Check that O-ring and its mating part are free of foreign
material.
 When installing O-ring, be careful 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, never insert it quickly into fuel tube.
 Insert new O-ring straight into fuel tube. Never twist it.
b. Install spacer (3) to fuel damper (4).
c. Insert fuel damper straight into fuel tube.
CAUTION:
 Insert straight, making sure that the axis is lined up.
 Never 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.

 Upper and lower O-ring are different. Be careful not to confuse them.
 Handle O-ring with bare hands. Never wear gloves.
 Lubricate O-ring with new engine oil.
 Never clean O-ring with solvent.
 Check that O-ring and its mating part are free of foreign material.
 When installing O-ring, be careful 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, never insert it quickly
into fuel tube.
 Insert O-ring straight into fuel injector. Never decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip (3) into clip mounting groove (F) on fuel injector (5).
 Insert clip so that protrusion (E) of fuel injector matches cutout
(C) of clip.
CAUTION:
 Never 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 mounting bolts in two steps in numerical order as
shown in the figure.
5. Connect fuel injector harness.
6. Install intake manifold collector. Refer to EM-28, "
Exploded View".
7. Connect quick connector between fuel feed hose and fuel tube connection with the following procedure:

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:
 Hold (A) position as shown in the figure 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 engagement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding (A) position. Check it is
completely engaged (connected) so that it does not come out
from fuel tube (2).
e. Install quick connector cap (3) to quick connector.
 Install quick connector cap with arrow on surface facing in
direction 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. Install in the reverse order of removal after this step.

INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there
are no fuel leakage at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start the engine. With engine speed increased, check again that there are no fuel leakage at connection
points.
CAUTION:
Never touch the engine immediately after stopped, as the engine becomes extremely hot.
