3. Disconnect fuel feed hose from hose clamp.
NOTE:
There is no fuel return path.
4. With the sleeve side of quick connector release facing quick connector, install quick connector release
onto fuel tube.
5. 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.
6. Draw and pull out quick connector straight from fuel tube.
CAUTION:
 Pull quick connector holding “A” position.
 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 installation/
removal.
 To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
7. Remove intake manifold. Refer to EM-156
