Removal and Installation: Installation

WARNING: This page is about a different car, the 2007 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Install the fuel rails with fuel injectors attached.
NOTE:
- Carefully install new O-rings, including the one used with the fuel damper.
- Lubricate O-rings by lightly coating with new engine oil.
- Be careful not to damage the O-rings and surfaces for O-ring sealing surfaces. Do not expand or twist O-rings.
- Discard old clips; replace with new ones.
- Make sure that protrusions of fuel injectors are aligned with cutouts of clips after installation.
- Position clips in grooves on the fuel injectors.
- Align the protrusions of the fuel tube assembly with those of the fuel injectors.
- After properly inserting the fuel injectors onto the fuel tube assembly, check that the fuel tube protrusions are engaged with those of fuel injectors, and the flanges of the fuel tube assembly are fully engaged with the clips.

Tighten fuel tube assembly bolts as shown, in two steps:
1st step: 10 N.m (1.0 kg-m, 7 ft-lb)

2nd step: 23.5 N.m (2.4 kg-m, 17 ft-lb)
CAUTION:
- After properly connecting fuel tube assembly to injector and fuel hose, check connection for fuel leakage.

Tighten the bolts of the intake manifold collector (upper) and electric throttle control actuator assembly diagonally to specification.
Intake manifold collector pipe bolts: 19.5 N.m (2.0 kg-m, 14 ft-lb)
After installation, it is necessary to re-calibrate the electric throttle control actuator.
- Perform "Throttle Control Closed Position Learning" when the harness connector of the electric throttle control actuator is disconnected. Refer to "THROTTLE VALVE CLOSED POSITION LEARNING ".
- Perform "Idle Air Volume Learning" when the electric throttle control actuator is replaced. Refer to "IDLE AIR VOLUME LEARNING ".
Attach the quick connector. Refer to "INSTALLATION ".
Installation of remaining components is in the reverse order of removal.
