• Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6.
Connect injector sub-harness.
7.
Install fuel sub tube mounting bolt.
8.
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, check that there is no gap between flange and fuel sub-tube.
9.
Connect quick connector between fuel feed hose (with damper) and centralized under-floor piping con-
nection as per the following:
a.
Check no foreign substances are deposited in and around centralized under-floor piping and quick con-
nector, 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.
• Visually confirm that the two retainer tabs (A) are connected to
the quick connector (B).
CAUTION:
• 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 position (A). Check it is
completely engaged (connected) so that it does not come out
from centralized under-floor piping (1).
