WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

Install fuel damper to each fuel tube.
1. Apply engine oil to O-ring and set it into the cap of fuel tube.
  CAUTION:
  - Handle O-ring with bare hands. Do not wear gloves.
  - Do not reuse O-ring.
  - 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.
  - Also be careful not to twist or stretch O-ring.
  - If O-ring was stretched while it was being attached, allow it to regain it's shape before inserting into fuel tube.
  - Insert O-ring straight into fuel tube. Do not angle or twist it.

2. Make sure that backup spacer is in the O-ring connecting surface of fuel damper.
  CAUTION: Do not reuse O-rings.
  
  NOTE: Backup spacer is fuel damper assembly part.
3. Insert fuel damper until it seats on fuel tube.
  CAUTION:
  - Insert straight, making sure that the axis is lined up.
  - Do not pressure-fit with excessive force.
  Reference value: 130 N (13.3 kg, 29.2 lb)
4. Install cap, and then tighten bolts evenly by turns.
  - After tightening bolts, make sure that there is no gap between cap and fuel tube.
Install O-rings to fuel injector paying attention to the items below.
CAUTION:
- Upper and lower O-ring are different.
  Standard model FFV model
  
  Fuel tube side: Blue Fuel tube side: Black
  
  Nozzle side: Brown Nozzle side: Green
- Handle O-ring with bare hands. Do not wear gloves.
- Do not reuse O-rings.
- 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.
- Also be careful not to twist or stretch O-ring.
- If O-ring was stretched while it was being attached, allow it to regain it's shape before inserting into fuel tube.
- Insert O-ring straight into fuel tube. Do not angle or twist it.
Install fuel injector to fuel tube.
1. Insert clip into clip mounting groove on fuel injector.
  - Insert clip so that lug (A) of fuel injector matches notch (A) of the 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.
    
    Do not reuse 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 lug (B) of fuel tube matches notch (B) of the clip.
  - Make sure that fuel tube flange is securely fixed in flange fixing groove on clip.
3. 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.

Install fuel hose assembly.
- Refer to precautions for fuel injector when handling O-ring.
  CAUTION: Do not reuse O-ring.
- Insert connectors straight, making sure that the axis is lined up with fuel tube side to prevent O-ring from being damaged.
- Tighten bolts evenly in several steps.
- Make sure that there is no gap between flange and fuel tube after tightening bolts.
Installation of the remaining components is in the reverse order of removal.
