• Do not clean O-ring with solvent.
• Check that O-ring and its mating pa
rt are free of foreign material.
• When installing O-ring, be careful not to scratch it.
• Do not twist or stretch O-ring. If O-ring was st retched while it was being attached, allow it to
retract before inserting it into fuel tube.
• Insert O-ring straight into fuel tube. Do not angle or twist it.
2. Install fuel injector (4) to fuel tube (1):
a. Insert new clip (2) into clip groove (G) on fuel injector (4). • Insert new clip (2) so that protrusion (F) of fuel injector
matches cut-out (D) 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 (4) into fuel tube (1) with clip (2) attached. • Insert fuel injector (4) while matching it to the axial center.
• Insert fuel injector (4) so that protrusion (B) of fuel tubematches cut-out (C) of clip (2).
• Check that fuel tube flange (A) is securely located in flange groove (E) on clip (2).
c. Check that installation is complete by checking that fuel injector (4) does not rotate or come off.
3. Set fuel tube and fuel injector assembly in position for installation on cylinder head. CAUTION:
For installation, be careful not to interfere with fuel injector nozzle.
• Tighten bolts in numerical order as shown.

6. Connect harness connectors to intake and ex haust valve timing control solenoid valves.
7. Connect fuel feed tube (engine side):
a. Check for damage or foreign material on the fuel tube and quick connector.
b. Apply new engine oil lightly to area around the top of fuel tube.
c. Align center to insert quick connector straight into fuel tube. • Insert quick connector (1) to fuel tube until the top spool (C) on
fuel tube is inserted completely and the 2nd level spool (D) is
positioned slightly below quick connector bottom end.
CAUTION:
• Hold in position (A) as sh own 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.
d. To avoid misidentification of engagement with a simi lar sound, pull quick connector hard by hand. Check it
is completely engaged (connected) so that it does not come out from fuel tube.
e. Install quick connector cap (engine side) (1) to quick connector connection.
• Install quick connector cap (engine side) (1) with the sidearrow facing quick connector side (fuel feed tube side) as
shown.
CAUTION:
• Check that the quick connector and fuel tube aresecurely engaged with the qu ick connector cap (engine
side) groove.
• If the quick connector cap (engine side) cannot be installed easily the quick connector may not be con-
nected correctly. Remove and reconnect.
f. Install fuel feed hose to hose clamp.
8. Connect fuel feed tube (floor piping side):

c. After connecting, check that the connection is secure:
• Visually confirm that the two retainer tabs are connected to theconnector.
• With the fuel feed hose not fix ed to the clamp, pull quick con-
nector (A) hard by hand to check that the quick connector (A)
is not disconnected from the centralized underfloor piping (1)
and that the quick connector (1) is securely connected.
9. Installation of remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there are no fuel leaks at connection points. Refer to.
NOTE:
Use mirrors for checking points out of clear sight.
2. Start the engine. With engine speed increased, check again that there are no fuel leaks at connection
points.
• Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
129, "Description".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-130, "
Description".
CAUTION:
Do not touch the engine immediately after stopping, as the engine becomes extremely hot.
