• Upper and lower O-rings are different colors.
• Handle O-ring with bare hands. Never wear gloves.
• Lubricate new 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 stretched while it was being attached, do not insert it quickly into fuel tube.
• Insert O-ring straight into fuel tube. Do not angle or twist it.
3. Install the fuel injector to the fuel tube.
a. Insert new clip into clip mounting groove on the fuel injector.
• Insert clip so that lug

of
the clip.
CAUTION:
• Do not reuse clip. Replace it with a new one.
• Do not allow the clip to interfere with the O-ring. If inter-
ference occurs, replace the O-ring.
b. Insert the fuel injector into the fuel tube with the clip attached.
• Insert it while matching it to the axial center.
• Insert fuel injector so that lug

of the clip.
• Make sure that the fuel tube flange is securely seated in the
flange fixing groove on the clip.
c. Make sure that installation is complete by checking that the fuel
injector does not rotate or come off.
• Make sure that the protrusions of the fuel injectors are aligned
with the cutouts of the clips after installation.

FUEL INJECTOR AND FUEL TUBE
4. Install the fuel tube and fuel injector assembly to the intake manifold.
CAUTION:
Do not let the tip of the injector nozzle come in contact with other parts.
• Tighten fuel tube assembly bolts

in illustration in two
steps.
5. Install the fuel hose assembly.
• Insert connectors straight, making sure that the axis is lined up with fuel tube side to prevent O-ring from
being damaged.
• Tighten bolts evenly in several steps.
• Make sure that there is no gap between the flange and fuel tube after tightening the bolts.
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 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 stretched while it was being attached, do not insert it quickly into fuel tube.
• Insert new O-ring straight into fuel tube. Do not twist it.
• Do not reuse O-rings.
6. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
After installing the fuel tubes, make sure there are no fuel leaks at the connections using the following steps.
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 the engine immediately after stopping, as engine becomes extremely hot.
NOTE:
Use mirrors for checking on hidden points.
