FUEL INJECTOR AND FUEL TUBE
Revision: 2006 July 2007 FX35/FX45

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 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 decenter or twist it.

Insert fuel damper and fuel sub-tube straight into fuel tube.

Tighten mounting bolts evenly in turn.

After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
2. Install new O-rings to fuel injector, paying attention to the following.
CAUTION:

Upper and lower O-ring are different. Be careful not to confuse them.

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

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 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 O-ring straight into fuel injector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
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.
4. Install spacers on intake manifold.
5. 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. Fuel tube side : Blue
Nozzle side : Brown

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect injector sub-harness.
7. Install intake manifold collectors (upper and lower). Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
8. Install fuel sub-tube on rear end of intake manifold collector (lower).
9. Connect fuel feed hose (with damper).

Handling procedure of O-ring is the same as that of fuel damper and fuel sub-tube.

Insert fuel damper straight into fuel sub-tube.

Tighten mounting bolts evenly in turn.

After tightening mounting bolts, make sure that there is no gap between flange and fuel sub-tube.
10. Connect quick connector between fuel feed hose (with damper) and centralized under-floor piping con- nection as follows:
a. Make sure no foreign substances are deposited in and around centralized under-floor piping and quick connector, and no damage on them.
b. Thinly apply new engine oil around centralized under-floor piping from tip end to spool end.
c. Align center to insert quick connector straightly into centralized under-floor piping.

Insert quick connector to centralized under-floor piping until
top spool is completely inside quick connector, and 2nd level
spool exposes right below quick connector.
CAUTION:

Hold “A” position as shown in the figure when inserting
centralized under-floor piping 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. Make sure it is completely engaged (connected) so that it does not come out from centralized under-floor piping.
e. Install quick connector cap to quick connector connection.

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 the
connection again.
11. Install in the reverse order of removal after this step. 1st step
: 10.1 N·m (1.0 kg-m, 7 ft-lb)
2nd step : 23.6 N·m (2.4 kg-m, 17 ft-lb)
