3. Disconnect fuel feed hose from hose clamp.
NOTE:
There is no fuel return path.
4. With the sleeve side of quick connector release facing quick connector, install quick connector release onto fuel tube.
5. 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.
6. 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.
7. Remove intake manifold. Refer to EM-141 .

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. If
interference 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
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.

a stopper pin.
17. Remove timing chain tensioner (1).
18. Remove timing chain slack guide (2), timing chain tension guide (3) and timing chain (1).
CAUTION:
Never rotate each crankshaft and camshaft individually
while timing chain is re moved. It causes interference
between valve and piston.
