4. Disconnect fuel feed hose from hose clamp.
NOTE:
There is no fuel return path.
5. With the sleeve side of quick connector release facing quick connector, install quick connector release onto fuel tube.
6. 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.
7. 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.

FUEL INJECTOR AND FUEL TUBE
9. Remove fuel tube bolts.
• Loosen bolts in reverse order as shown.
10. Remove the fuel tube and fuel injector assembly. CAUTION:
• When removing, be careful to avoid any interference with fuel injector.
• Use a shop cloth to absorb any fuel leaks from fuel tube.
11. Remove fuel injector from the f uel tube with the following procedure:
a. Open and remove the clip.
b. Remove fuel injector from the fuel tube by pulling straight. CAUTION:
• Be careful about spilling fu el remaining in fuel tube.
• Be careful not to damage the fuel injector nozzle during removal.
• Never bump or drop fuel injector.
• Never disassemble fuel injector.
INSTALLATION
1. Install new O-rings to the fuel injector.
CAUTION:
• The upper and lower O-rings are different. Be careful not to confuse them.
• Handle O-ring with bare hands. Never wear gloves.
• Lubricate O-ring with new engine oil.
• Never clean O-ring with solvent.
• Make sure that the O-ring and its mati ng part are free of foreign material.
• Be careful not to scratch O-ring with tool or fingernails when installing.

2. Install fuel injector (4) to fuel tube (1) with the following proce-
dure:
a. Insert clip (2) into clip groove (F) on fuel injector. • Insert clip so that protrusion (G) of fuel injector matches cut-
out (D) of clip.
CAUTION:
• Never reuse clip. Replace it with a new one.
• Be careful to keep clip from interfering with O-ring. Ifinterference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached. • Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion (B) of fuel tube matches
cut-out (C) of clip.
• Make sure that fuel tube flange (A) is securely fixed in flange
fixing groove (E) on clip.
c. Make sure that installation is complete by making sure that fuel injector does not rotate or come off.
3. Set fuel tube and fuel injector assembly at its position for installation on cylinder head. CAUTION:
Be careful not to let tip of injector nozzle interfere with other parts.
4. Tighten bolts in numerical order as shown.
5. 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.
