FUEL INJECTOR AND FUEL TUBE
Revision: 2005 July 2005 FX

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
