Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect injector sub-harness.
7. Install intake manifold collectors (upper and lower). Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
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 con- nection 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 pre-
vent 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.

Install quick connector cap with arrow 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 the
connection again.
11. Install in the reverse order of removal after this step. 1st step
: 10.1 N·m (1.0 kg-m, 7 ft-lb)
2nd step : 23.6 N·m (2.4 kg-m, 17 ft-lb)
