a. Remove quick connector cap (1) from quick connector connec-
tion.
b. Disconnect fuel feed hose from hose clamp.
c. With the sleeve side of quick connector release facing quick connector, install quick connector release onto fuel tube.
d. Insert quick connector release 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.
e. Draw and pull out quick connector straight from fuel tube. CAUTION:
• Pull quick connector holding “A” position.
• 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.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick co nnector and fuel feed hose during installation/
removal.
• To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
4. Disconnect harness connector from fuel injector.
5. Remove fuel tube protector. • Loosen bolts in the reverse of the order shown. KBIA0702E

2. Install the fuel injector (4) onto the fuel tube (1) with the following
procedure:
a. Insert the clips (2) into the clip mounting grooves on the fuel injector.
• Insert clip cut-out (D) into fuel injector protrusion (F). CAUTION:
• Always replace clip with new one.
• Make sure that the clip do es not interfere with the O-
ring. If interference occurs, replace the O-ring.
b. Insert the fuel injector into the fuel tube with clip attached. • Make sure that the axis is lined up when inserting.
• Insert clip cut-out (C) into fuel tube protrusion (B).
• Make sure that the flange (A) on the fuel tube fits securely in the clip flange fixing groove (E).
c. Make sure that installation is complete by checking that fuel injector does not rotate or come off.
3. Install fuel tube and injector assembly onto cylinder head. • Tighten bolts in the numerical order shown.
CAUTION:
Be careful not to let tip of injector nozzle interfere with
other parts.
4. Install fuel tube protector. • Tighten bolts in the numerical order shown.
5. Connect harness connector to fuel injector.
6. Connect fuel feed hose with the following procedure.
a. Check for damage or foreign material on the fuel tube and quick connector.

c. Align center to insert quick connector straightly into fuel tube. • Insert quick connector to fuel tube until the top spool on fueltube is inserted completely and the 2nd level spool is posi-
tioned slightly below quick connector bottom end.
CAUTION:
• Hold “A” position shown 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.
• To avoid misidentification of engagement with a similar sound, be sure to pe rform the next step.
d. Before clamping fuel feed hose with hose clamp, pull quick connector hard by hand holding “A” position.
Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
e. Install quick connector cap (1) to quick connector connection. • Install quick connector cap with the side arrow facing quick
connector side (fuel feed hose side).
CAUTION:
• Make sure that the quick connector and fuel tube are
securely engaged with the quick connector cap mount-
ing groove.
• Quick connector may not be connected correctly if quick connector cap cannot be installed easily. Remove
the quick connector cap, and then check the connection
of quick connector again.
f. Install fuel feed hose to hose clamp.
7. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, make sure
there are no fuel leaks at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start the engine. With engine speed increased, make su re again that there are no fuel leaks at connection
points.
CAUTION:
Never touch the engine immediately after it is stopped, as the engine becomes extremely hot. KBIA0272E
