 When handling new O-rings, be careful of the following caution.
CAUTION:
 Handle O-ring with bare hands. Do not wear gloves.
 Lubricate O-ring with new engine oil.
 Do not clean O-ring with solvent.
 Make sure that O-ring an d its mating part are free of foreign material.
 When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not
to twist or stretch O-ring. If O-ring was stretc hed while it was being attached, do not insert it
quickly into fuel tube.
 Insert new O-ring strai ght into fuel tube. Do not decenter or twist it.
 Insert fuel feed damper straight into fuel tube (RH).
 Tighten mounting bolts evenly in turn.
 After tightening mounting bolts, make sure that there is no gap between flange and fuel tube (RH).
2. Install new O-rings to fuel injector paying attention to the following caution. CAUTION:
 Upper and lower O-ring are different . Be careful not to confuse them.
 Handle O-ring with bare hands. Never wear gloves.
 Lubricate O-ring with new engine oil.
 Do not clean O-ring with solvent.
 Make sure that O-ring and its mating part are free of foreign material.
 When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretche d while it was being attached, do not insert it
quickly into fuel tube.
 Insert O-ring straight into fuel in jector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip into clip mounting groove on fuel injector.  Insert clip so that “protrusion A” of fuel injector matches “cut-
out A” of clip.
CAUTION:
 Do not reuse clip. Replace it with a new one.
 Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.  Insert it while matching it to the axial center.
 Insert fuel injector so that “p rotrusion B” of fuel tube matches
“cutout B” of clip.
 Make sure that fuel tube flange is securely fixed in flange fixing
groove on clip.
c. Make sure that installation is complete by checking that fuel injector does not rotate or come off.
 Make sure that protrusions of fuel injectors are aligned with
cutouts of clips after installation.
4. Install spacers on intake manifold (lower).

FUEL INJECTOR AND FUEL TUBE
 Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel feed hose on engine side as follows: (Unless otherwise indicated, the installation to the engine side and centralized under-floor piping side is exactly alike.)
a. Make sure no foreign substances are deposited in and around fuel tube and quick connector, and no dam- age on them.
b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube. Engine side:
 Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector.
CAUTION:
 Hold “A” position as shown in the figure when inserting
fuel tube 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 si milar sound, be sure to perform the next step.
Centralized under-floor piping side:
 Visually confirm that the two retainer tabs are connected to the connector.
CAUTION:
 Carefully align center to avoid inclined insertion to prevent dama ge to O-ring inside quick con-
nector.
 Insert until you hear a “click” soun d and actually feel the engagement.
 To avoid misidentification of engagement with a si milar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Make su re it is completely engaged (connected) so that it
does not come out from fuel tube.
e. Install quick connector cap on quick connector connection. CAUTION:
If cap cannot be installed smoothly, quick connector may
have not been installed corr ectly. Check connection again.
f. Install fuel feed hose to hose clamps.
7. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
