CAUTION:
Perform this step when the engine is cold.
5. Remove fuel feed hose (with damper) from fuel sub-tube.

quick connector as follows:
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 follows:
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.

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-

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel feed hose on engine side as follows: (Unless otherwise indicated, the installation to the
engine side and centralized under-floor piping side is exactly alike.)
a. Make sure no foreign substances are deposited in and around fuel tube and quick connector, and no dam-
age on them.
b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube.
Engine side:
Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector.
CAUTION:
Hold “A” position as shown in the figure 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.
Centralized under-floor piping side:
Visually confirm that the two retainer tabs are connected to the connector.
CAUTION:
Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick con-
nector.
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. Pull quick connector by hand holding position. Make sure it is completely engaged (connected) so that it
does not come out from fuel tube.
e. Install quick connector cap on quick connector connection.
CAUTION:
If cap cannot be installed smoothly, quick connector may
have not been installed correctly. Check connection again.
f. Install fuel feed hose to hose clamps.
7. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
