6. Connect fuel injector harness connector.
7. Install intake manifold collectors (upper and lower). Refer to EM-133, "
INTAKE MANIFOLD COLLECTOR"
.
8. Connect fuel feed hose (with damper).

Handling procedure of O-ring is the same as that of fuel damper.

Insert fuel damper straight into fuel tube.

Tighten mounting bolts evenly in turn.

After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
9. 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.

Install quick connector cap with arrow on surface facing in
direction of quick connector [fuel feed hose (with damper)
side].
CAUTION:
If quick connector cap cannot be installed smoothly, quick
connector may have not been installed correctly. Check
connection again.
10. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check Fuel Leakage
1. Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start engine. With engine speed increased, check again for fuel leakage at connection points.
CAUTION:
Do not touch engine immediately after stopped, as engine becomes extremely hot.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluid leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

Warm up engine thoroughly to make sure there is no leakage of exhaust gases, or any oil/fluids including
engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
