4. 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.
5. 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 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.

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.
