FUEL INJECTOR AND FUEL TUBE
9. Remove fuel injector from fuel tube as follows:
a. Carefully open and remove clip.
b. Remove fuel injector from fuel tube by pulling straight.
CAUTION:
• Be careful with remaining fuel that may leak out from fuel
tube.
• Do not damage injector nozzles during removal.
• Do not bump or drop fuel injectors.
• Do not disassemble fuel injectors.
10. Disconnect fuel tube (RH) from fuel tube (LH).
11. Loosen bolts, to remove fuel damper cap and fuel damper, if necessary.
INSTALLATION
1. Install fuel damper as follows:
a. Install new O-ring to fuel tube as shown.
• When handling new O-rings, be careful of the following cau-
tion:
CAUTION:
• 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 for-
eign material.
• When installing O-ring, do not scratch it with tool or fin-
gernails.
• 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.
b. Install spacer to fuel damper.
c.
Insert fuel damper straight into fuel tube.
CAUTION:
• Insert straight, making sure that the axis is lined up.
• Do not pressure-fit with excessive force.
• Insert fuel damper until (B) is touching (A) of fuel tube.
d. Tighten bolts evenly in turn.
• After tightening bolts, make sure that there is no gap between fuel damper cap and fuel tube.
2. Install new O-rings to fuel injector, paying attention to the following.
CAUTION:
• Do not reuse O-rings.

• 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.
• 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 to fuel tube.
a. Insert clip into clip mounting groove on the fuel injector.
• Insert new clip so that protrusion of fuel injector matches cut-
out of 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 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 protrusion of fuel tube matches cut-
out of clip.
• Make sure that fuel tube flange is securely fixed in flange fixing
groove on clip.
c. Make sure that the installation is complete by checking that the
fuel injector does not rotate or come off.
• Make sure that protrusions of the fuel injectors are aligned
with cutouts of clips 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.
• 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.

• Tighten bolts in two steps in numerical order as shown.
6. Tighten bolts which connects 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-27, "Removal and Installation"
.
9. 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 engine immediately after stopping, as engine becomes extremely hot.
NOTE:
Use mirrors for checking on hidden points.
