3. Disconnect fuel feed hose on engine side as follows: (Perform
same procedure for the side of centralized under-floor piping as
well.)
a. Remove quick connector cap from quick connector connection.
b. Disconnect quick connector from fuel feed damper as follows:
CAUTION:
Disconnect quick connector by using quick connector release [S ST: J-45488], not by picking out
retainer tabs (centralized under-floor piping side).
i. With the sleeve side of quick connector release facing to quick connecto\
r, install quick connector release onto fuel tube.
ii. Insert quick connector releas e into quick connector until sleeve
contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector re lease hard will not disconnect
quick connector. Hold qui ck connector release where it
contacts and goes no further.

 Do not pull with lateral force applied. O-ring inside quick connector may be damaged.
 Prepare container and cloth be forehand as fuel will leak out.
 Avoid fire and sparks.
 Keep parts away from heat source. Especially, be careful when welding is performed around
them.

 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).
5. Install fuel tube and fuel injector assembly to intake manifold (lower). CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts.
