Removal and Installation: Installation

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install fuel damper as follows:
    1. Install new O-ring (2) to fuel tube (1) as shown. When handling new O-ring, be careful of the following caution:
      CAUTION:
      • Handle O-ring with bare hands. Never wear gloves.
      • Lubricate O-ring with new engine oil.
      • Never 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, never insert it quickly into fuel tube.
      • Insert new O-ring straight into fuel tube. Never twist it.
    2. Install spacer (3) to fuel damper (4).
    3. Insert fuel damper straight into fuel tube.
      CAUTION:
      • Insert straight, checking that the axis is lined up.
      • Never pressure-fit with excessive force.

        Reference value: 130 N (13.3 kg, 29.2 lb) 

      • Insert fuel damper until (B) is touching (A) of fuel tube.

    4. Tighten bolts evenly in turn.
      • After tightening bolts, check that there is no gap between fuel damper cap (5) 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.

      Fuel tube side: Black 

      Nozzle side: Green 

    • Handle O-ring with bare hands. Never wear gloves.
    • Lubricate O-ring with new engine oil.
    • Never 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, never insert it quickly into fuel tube.
    • Insert O-ring straight into fuel injector. Never decenter or twist it.
  3. Install fuel injector to fuel tube as follows:
    1. Insert clip (3) into clip groove (F) on fuel injector (5).
      • Insert clip so that protrusion (E) of fuel injector matches cutout (C) of clip.
        CAUTION:
        • Never reuse clip. Replace it with new one.
        • Be careful to keep clip from interfering with O-ring. If interference occurs, replace O-ring.
    2. 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.
    3. 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.

  4. 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 bolts in two steps in numerical order as shown in the figure.

      1st step: 10.1 N.m (1.0 kg-m, 7 ft-lb) 

      2nd step: 22.0 N.m (2.2 kg-m, 16 ft-lb) 

  5. Connect fuel injector harness.
  6. Install intake manifold collector. Refer to "REMOVAL AND INSTALLATION ".
  7. Connect quick connector between fuel feed hose and fuel tube connection with the following procedure:
    1. Check no foreign substances are deposited in and around fuel tube and quick connector, and no damage on them.
    2. Thinly apply new engine oil around fuel tube from tip end to spool end.
    3. Align center to insert quick connector straightly 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.
      CAUTION:
      • Hold (A) position as shown in the figure 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.
    4. Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does not come out from fuel tube.
    5. Install quick connector cap (3) to quick connector.
      • 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.
    6. Secure fuel feed hose to clamp of quick connector cap.
  8. Installation is in the reverse order of removal.
