d valve connector with it facing front of engine.

nally in several steps.

Connecting Quick Connector of Fuel Tube
Install quick connector as follows (the steps are the same for quick connectors on both engine side and vehi-
cle side except for the quick connector cap).
1. Make sure no foreign substances are deposited in and around tube and quick connector, and they are not
damaged.
2. Thinly apply new engine oil around the fuel tube from tip end to the spool end.
3. Align center to insert quick connector straight into fuel tube. • Insert until the paint mark for engagement identification (white)
goes completely inside quick connector so that you cannot see
it from the straight side of the connected part. Use a mirror to
check this where it is not possible to view directly from the
straight side, such as quick connector on vehicle 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 on engine side.
CAUTION:
• Hold "A" position in illustration when inserting fuel tubeinto 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.
4. Pull quick connector by hand holding "A" position. Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
