FX35 AWD V6-3.5L (VQ35DE) (2006)
4. Install spacers on intake manifold.
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.
^
Tighten mounting bolts in two steps in numerical order as shown in the figure.
1st step: 10.1 Nm (1.0 kg-m, 7 ft. lbs.)
2nd step: 23.6 Nm (2.4 kg-m, 17 ft. lbs.)
6. Connect injector sub-harness.
7. Install intake manifold collectors (upper and lower).
8. Install fuel sub-tube on rear end of intake manifold collector (lower).
9. Connect fuel feed hose (with damper).
^
Handling procedure of O-ring is the same as that of fuel damper and fuel sub-tube.
^
Insert fuel damper straight into fuel sub-tube.
^
Tighten mounting bolts evenly in turn.
^
After tightening mounting bolts, make sure that there is no gap between flange and fuel sub-tube.
10. Connect quick connector between fuel feed hose (with damper) and centralized under-floor piping connection as follows:
a. Make sure no foreign substances are deposited in and around centralized under-floor piping and quick connector, and no damage on them.
b. Thinly apply new engine oil around centralized under-floor piping from tip end to spool end.
c. Align center to insert quick connector straightly into centralized under-floor piping.
^
Insert quick connector to centralized under-floor piping until top spool is completely inside quick connector, and 2nd level spool exposes
right below quick connector.
CAUTION:
^
Hold A position as shown in the figure when inserting centralized under-floor piping 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.
d. Pull quick connector by hand holding A position. Make sure it is completely engaged (connected) so that it does not come out from centralized
under-floor piping.
e. Install quick connector cap to quick connector connection.
