a. Remove quick connector cap (engine side).
b. With the sleeve side of quick connector release facing quick connector, install quick connector release
onto fuel tube.
c. Insert quick connector release into quick connector until sleeve
contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
d. Draw and pull out quick connector straight from fuel tube.
CAUTION:

Pull quick connector holding “A” position in the figure.

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 during installa-
tion/removal.

To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
4. Remove PCV hose. Refer to EM-19, "
INTAKE MANIFOLD" .
5. Disconnect harness connector from ignition coil.
6. Remove sub-harness for fuel injector.
7. Remove electric throttle control actuator and intake manifold support. Refer to EM-19, "

2. Install fuel injector to fuel tube with the following procedure:
a. Insert clip into clip mounting groove on fuel injector.

Insert clip so that protrusion “A” of fuel injector matches cutout
“A” of 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 protrusion “B” of fuel tube matches
cutout “B” of clip.

Make sure that fuel tube flange is securely fixed in flange fix-
ing 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.
3. From the engine rear side, set fuel tube and fuel injector assembly at its position for installation on intake
manifold.
CAUTION:
When installing, be careful to avoid any interference with fuel injector.
4. Set fuel tube protector onto fuel tube.
5. Tighten mounting bolts with the following procedure.

Tighten bolts evenly in two steps in numerical order as shown
in the figure.
6. Connect sub-harness for fuel injector.
7. Note the following, and connect quick connectors at engine side and vehicle side to install fuel feed hose.
NOTE:
There is quick connector for the engine side and for the vehicle side, and they have different shapes. But
connection is same procedure. The following procedure shows the engine side.
a. Check the connection for foreign material and damage.
b. Align center to insert quick connector straightly into fuel tube.

Insert quick connector to fuel tube until the top spool on fuel
tube is inserted completely and the second level spool is posi-
tioned slightly below quick connector bottom end.
CAUTION:

Hold “A” position 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.
c. Before clamping fuel feed hose with hose clamps, pull quick connector hard by hand holding “A” position.
Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
d. Install quick connector cap to quick connector connection. (On
both the engine side and the vehicle side)

Install so that the arrow mark on the side faces up.
CAUTION:

Make sure that quick connector and fuel tube are
securely fit into quick connector cap installation groove.

If quick connector cap cannot be installed smoothly,
quick connector may have not been installed correctly.
Check connection again.
NOTE:
There is quick connector cap for the engine side and for the
vehicle side, and they have different shapes. The figure shows engine side as an example.
8. Install fuel feed hose to hose clamp.
9. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then make sure
there are no fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
2. Start engine. With engine speed increased, make sure again there are no fuel leaks at connections.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.
