3.
Disconnect quick connector with the following procedure. Dis-
connect fuel feed hose from fuel tube.
NOTE:
There is no fuel return path.
a.

c.
With the sleeve side of quick connector release facing quick connector, install quick connector release
(commercial service tool) onto fuel tube.
d.
Insert quick connector release (A) into quick connector (2) until
sleeve (B) contacts and goes no further. Hold quick connector
release on that position.

CAUTION:
• Pull quick connector (E) holding position (C) in the figure.
• Never pull with lateral force applied. O-ring inside quick connector may be damaged.
• Prepare container and cloth beforehand as fuel will leakage out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Never expose parts to battery electrolyte or other acids.
• Never bend or twist connection between quick connector and fuel feed tube during installation/

tion.
• When the lever hole is aligned with the body hole position, the
plunger is fixed.
• When the protrusion parts of the plunger ratchet and the tab
face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c.
