- 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.
- Install spacer (3) to fuel damper (4).
- Insert fuel damper straight into fuel tube.
- Tighten bolts evenly in turn.
- After tightening bolts, check that there is no gap between fuel damper cap (5) and fuel tube.
- Install new O-ring (2) to fuel tube (1) as shown, below. When handling new O-ring, be careful of the following:
- Install new O-rings to fuel injector paying attention to the following.CAUTION:
- Do not reuse O-rings.
- Upper and lower O-rings are different. Be careful not to confuse them.
Fuel tube side
: Black
Nozzle side
: Green
- Handle O-ring with bare hands. Do not wear gloves.
- Lubricate O-ring with new engine oil.
- Do not clean O-ring with solvent.
- Check 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 twist it.
- Install fuel injector to fuel tube as follows:
- Insert clip (3) into clip groove (F) on fuel injector (5).
(2)
: O-ring (black)
(4)
: O-ring (green)
- Insert clip so that protrusion (E) of fuel injector matches cutout (C) of clip.CAUTION:
- Do not reuse O-rings.
- Do not reuse clip. Replace it with new one.
- Be careful to keep clip from interfering with O-ring. If interference occurs, replace O-ring.
- Insert clip so that protrusion (E) of fuel injector matches cutout (C) of clip.
- 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.
- 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.
- Insert clip (3) into clip groove (F) on fuel injector (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.
- Connect fuel injector harness.
- Install intake manifold collector. Refer to Removal and Installation .
- Connect quick connector between fuel feed hose and fuel tube connection with the following procedure:
- Check no foreign substances are deposited in and around fuel tube and quick connector, and that there is no damage on them.
- Thinly apply new engine oil around fuel tube from tip end to spool end.
- Align center to insert quick connector straight 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.
(B)
: Installed condition
: Upright insertion
CAUTION:- Do not reuse O-ring.
- Hold (A) position as shown above, when inserting fuel tube into quick connector.
- Carefully align center to avoid inclined insertion to prevent 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.
- 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.
- Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does not come out from fuel tube.
- Install quick connector cap (3) to quick connector.
(1)
: Fuel feed hose
(2)
: Fuel tube
(B)
: Upper view
- 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. - Secure fuel feed hose to clamp of quick connector cap.
- Installation of the remaining components is in the reverse order of removal.
