FUEL INJECTOR AND FUEL TUBE

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-33, "Exploded View"

.

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.

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:

• 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.

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 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.
