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 does 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.

c. Align center to insert quick connector straightly into fuel tube.
 Insert quick connector to fuel tube until the top spool on fuel
tube 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 perform 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 is in the reverse order of removal, for the remaining parts.

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 sure again that there are no fuel leaks at connection
points.
CAUTION:
Never touch the engine immediately after stopped, as the engine becomes extremely hot.
