Removal and Installation: Installation

WARNING: This page is about a different car, the 2013 Infiniti FX50. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Do not reuse O-rings.
  1. Install fuel damper (4) as per the following:

    1. Install new O-ring (3) to fuel tube (bank 1) (2) as shown. When handling new O-ring, pay attention to the following caution items:
      CAUTION:
      • Do not reuse O-ring.
      • 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 de-center or twist it.
    2. Install spacer (A) to fuel damper. Insert fuel damper straight into fuel tube (bank 1).
      CAUTION:
      • Insert straight, check that the axis is lined up.
      • Insert fuel damper at 130 N (13.3 kg, 29.2 lb) or less to prevent damage to the parts
      • Insert fuel damper until the rim (C) reaches the cap flange (B).
    3. Tighten mounting bolts evenly in turn.
      • After tightening mounting bolts, check that there is no gap between flange and fuel tube (bank 1).
  2. Install fuel feed damper.
    • Handling procedure of O-ring is the same as that of fuel damper.
    • Insert fuel feed damper straight into fuel tube (bank 2).
      CAUTION: Insert fuel feed damper at 147 N (15 kg, 33.1 lb) or less to prevent damage to the parts
    • Tighten mounting bolts evenly in turn.
    • After tightening mounting bolts, check that there is no gap between flange and fuel tube (bank 2).
  3. Install new O-rings to fuel injector paying attention to the following caution.
    CAUTION:
    • Do not reuse O-rings.
    • 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 de-center or twist it.
  4. Install fuel injector (3) to fuel tube (1) as per the following:
    Fig 2: Locating Fuel Injector And Fuel Tube Components

    1. Insert clip (5) into clip mounting groove (B) on fuel injector.
      • Insert clip so that protrusion (C) of fuel injector matches cutout (E) of clip.
        CAUTION:
        • Never reuse clip. Replace it with a 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 with clip attached.
      • Insert it while matching it to the axial center.
      • Insert fuel injector so that protrusion (G) of fuel tube matches cutout (F) of clip.
      • Check that fuel tube flange (A) is securely fixed in flange fixing groove (D) on clip.
        CAUTION: Insert fuel injector at 147 N (15 kg, 33.1 lb) or less to prevent damage to the parts
    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 tube are aligned with cutouts of clips after installation.
  5. Install fuel tube and fuel injector assembly.
    • Tighten mounting bolts (a) first. Then tighten mounting bolts (b) shown in the figure below.

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

      Torque Value: 2nd step: 23.6 N.m (2.4 kg-m, 17 ft-lb) 

      CAUTION:
      • Be careful not to let tip of injector nozzle come in contact with other parts.
      • Insert fuel injector at 147 N (15 kg, 33.1 lb) or less to prevent damage to the parts
  6. Install quick connectors as per the following:
    • Unless otherwise indicated, the installation to the engine side and centralized under-floor piping side is exactly alike.
    1. Check no foreign substances are deposited in and around fuel piping and quick connector, and no damage on them.
    2. Thinly apply new engine oil around fuel piping from tip end to spool end.
    3. Align center to insert quick connector straightly into fuel piping.

      Fuel hose (center) and centralized under-floor piping side: 

      • Visually confirm that the two retainer tabs (A) are connected to the quick connector (B).
        CAUTION:
        • 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.

      Fuel feed damper side: 

      • Insert quick connector to fuel feed damper piping until top spool (2) is completely inside quick connector and 2nd level spool (3) exposes just below quick connector.

      CAUTION:
      • Hold (A) position as shown in the figure below, when inserting fuel feed hose (1) 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 (A). Check it is completely engaged (connected) so that it does not come out from fuel piping (1).

      • Install quick connector cap with arrow (A) on surface facing the direction of quick connector.
        CAUTION: If cap cannot be installed smoothly, quick connector may have not be installed correctly. Check connection again.
        NOTE: Figure shows an example fuel feed damper side.
  7. Install in the reverse order of removal.
