The cold type spark plug is suitable when spark knock occurs with the standard type spark plug under condi-
tions such as:

Extended highway driving

Frequent high engine revolution

FUEL INJECTOR AND FUEL TUBE
Revision: 2004 November 2004 FX35/FX45
REMOVAL
1. Remove engine cover with power tool. Refer to EM-19, "INTAKE MANIFOLD COLLECTOR" .
2. Release fuel pressure. Refer to EC-51, "
FUEL PRESSURE RELEASE" .
3. Remove fuel feed hose (with damper) from fuel sub-tube.
NOTE:
There is no fuel return route.
CAUTION:

While hoses are disconnected, plug them to prevent fuel
from draining.

Do not separate damper and hose.
4. When separating fuel feed hose (with damper) and centralized under-floor piping connection, disconnect
quick connector as the following:
a. Remove quick connector cap from quick connector connection
on right member side.
b. Disconnect fuel feed hose (with damper) from bracket hose
clamp.
c. Disconnect quick connector from centralized under-floor piping as the following:
CAUTION:
Disconnect quick connector by using quick connector release [SST: — (J-45488)], not by picking
out retainer tabs.
i. With the sleeve side of quick connector release facing quick connector, install quick connector release
onto centralized under-floor piping.
ii. 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 release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
iii. Draw and pull out quick connector straight from centralized
under-floor piping.
CAUTION:

Pull quick connector holding “A” position as shown in
the figure.

Do not pull with lateral force applied. O-ring inside quick connector may be damaged.

Prepare container and cloth beforehand 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 connector and fuel feed hose (with damper) dur-
ing installation/removal.

5. Install fuel tube and fuel injector assembly to intake manifold.
CAUTION:
Be careful not to let tip of injector nozzle come in contact
with other parts.

Tighten mounting bolts in two steps in numerical order shown
in figure.
6. Connect injector sub-harness.
7. Install intake manifold collector (upper and lower). Refer to EM-
19, "INTAKE MANIFOLD COLLECTOR" .
8. Install fuel sub-tube on rear end of intake manifold collector (lower).
9. Connect fuel feed hose (with damper).

Handling procedure of O-ring is the same as that of fuel damper and fuel sub-tube.

Insert fuel damper straight into fuel sub-tube.

Tighten mounting bolts evenly in turn.

After tightening mounting bolts, make sure that there is no gap between flange and fuel sub-tube.
10. Connect quick connector between fuel feed hose and centralized under-floor piping connection with the
following procedure:
a. Check the connection for damage and foreign materials.
b. Align connector with tube, then insert connector straight into tube until a click is heard.
c. After connecting quick connector, use the following method to
make sure it is full connected.

Visually confirm that the two retainer tabs are connected to
connector.

Pull tube and connector to make sure they are securely con-
nected.
d. Install quick connector cap to quick connector connection.

Install quick connector cap with arrow on surface facing in
direction of quick connector (fuel feed hose side).
CAUTION:
If cap cannot be installed smoothly, quick connector may
have not been installed correctly. Check connection
again.
e. Secure fuel feed hose to clamp.
11. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leakage

After installing fuel tubes, make sure there is no fuel leakage at connections in the following steps.
–a) Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then check for
fuel leaks at connections.
–b) Start engine and rev it up and check for fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points. 1st step: 10.1 N·m (1.0 kg-m, 7 ft-lb)
2nd step: 23.6 N·m (2.4 kg-m, 17 ft-lb)
