INSTALLATION
1. Install fuel damper as follows:
a. Install new O-ring to fuel tube as shown.

When handling new O-ring, be careful of the following cau-
tion:
CAUTION:

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 twist it.
b. Install spacer to fuel damper.
c. Insert fuel damper straight into fuel tube.
CAUTION:

Insert straight, making sure that the axis is lined up.

Do not pressure-fit with excessive force.

Insert fuel damper unit “B” is touching “A” of fuel tube.
d. Tighten bolts evenly in turn.

After tightening bolts, make sure that there is no gap between fuel damper cap and fuel tube.
2. Install fuel sub-tube.

When handling new O-ring, be careful of the following caution:
CAUTION:

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 tube. Do not decenter or twist it.

Insert 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 sub-tube.

FUEL INJECTOR AND FUEL TUBE
Revision: 2006 November2007 350Z

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.

4. Install fuel injector to fuel tube as follows:
a. Insert clip (3) into clip mounting groove (D) on fuel injector (5).
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 (5) into fuel tube (1) with clip attached.

Insert it while matching it to the axial center.

Insert fuel injector (5) so that protrusion (A) of fuel tube
matches cutout (B) of clip (3).

Make sure that fuel tube flange (E) is securely fixed in flange
fixing groove (C) on clip (3).
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.
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.

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel injector harness connector.
7. 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.
8. 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.
