CAUTION:
• Do not reuse O-rings.
• Upper and lower O-ring are different colors.
• 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 and its mating part are free of foreign material.
• When installing O-ring, be careful not to scratch it with tool or fingernails.
• Do not twist or stretch O-ring. If O-ring was stretched while it was being attached, allow it to
retract before inserting it into fuel tube.
• Insert O-ring straight into fuel injector. Do not angle or twist it.
3. Install fuel injector (5) to fuel tube (1).
a. Insert new clip (3) into clip mounting groove (E) on fuel injector
(5).
• Insert clip (3) so that protrusion of fuel injector matches cutout
(C) of clip.
CAUTION:
• Do not reuse O-ring (2 and 4).
• Do not reuse clip. Replace it with a new one.
• Do not allow the clip (3) to interfere with the O-ring (2). If
interference occurs, replace O-ring.
b. Insert fuel injector (5) into fuel tube (1) with clip (3) attached.
• Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion of fuel tube (A) matches
cutout of clip (3).
• Make sure that fuel tube flange (F) is secured in flange attach-
ing groove (D) on clip (3).
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 (5) are aligned with
cutouts of clips (B) after installation.
4. Connect the fuel tube (RH) to the fuel tube (LH), and tighten bolts temporarily.
• Tighten bolts to the specified torque after installing fuel tube and fuel injector assembly.
CAUTION:
• Handle O-ring with bare hands. Do not wear gloves.
• Do not reuse O-rings.
• 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.
• Do not twist or stretch O-ring. If O-ring was stretched while it was being attached, allow it to
retract before inserting it into fuel tube.
• Insert new O-ring straight into fuel tube. Do not angle or twist it.
5. Install fuel tube and fuel injector assembly to intake manifold.
CAUTION:
Do not let the tip of the injector nozzle come in contact with other parts.

FUEL INJECTOR AND FUEL TUBE
• Tighten bolts in two steps in numerical order as shown.
6. Tighten bolts which connect fuel tube (RH) and fuel tube (LH) to the specified torque.
7. Connect fuel injector harness connector.
8. Install intake manifold collector. Refer to
EM-142, "Removal and Installation"
9. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Apply fuel pressure to the fuel lines by turning ignition switch ON (with engine stopped). Then check for
fuel leaks at the connections.
2. Start the engine and rev it up and check for fuel leaks at the connections.
WARNING:
Do not touch engine immediately after stopping, as engine becomes extremely hot.
NOTE:
Use mirrors for checking at points out of clear sight.
