FUEL INJECTOR AND FUEL TUBE
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) in to 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.
b. Apply new engine oil lightly to area around the top of fuel tube.

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 quickconnector side (fuel feed hose side).
CAUTION:
• Make sure that the quick connector and fuel tube aresecurely 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, an d 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
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
