3. Disconnect fuel feed hose on engine side as follows: (Excepting
to confirm whether or not there is quick connector cap, perform
same procedure for the side of centralized under-floor piping as
well.)
a. Remove quick connector cap from quick connector connection. (engine side only)
b. Disconnect quick connector from fuel feed damper as follows: CAUTION:
Disconnect quick connector by using quick connector release [SST: J-45488], not by picking out
retainer tabs (centralized under-floor piping side).
i. With the sleeve side of quick connector release facing to quick connector, install quick connector release onto fuel tube.
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 fuel damper. 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 during installa-
tion/removal.
