2.
Install fuel injector to fuel tube.
a.
Insert clip into clip mounting groove on fuel injector.
• Insert new clip so that protrusion of fuel injector matches cut-
out of clip.
CAUTION:
• Do not reuse clip. Replace it with a new one.
• Do not allow the clip to interfere with the O-ring. If interfer-
ence occurs, replace O-ring.
b.
Insert the fuel injector into the fuel tube with the clip attached.
• Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion of fuel tube matches cut-
out of clip.
• Make sure that fuel tube flange is securely fixed in flange fixing
groove on clip.
c.
Make sure that installation is complete by checking that the fuel
injector does not rotate or come off.
• Make sure that protrusions of the fuel injectors are aligned
with cutouts of clips after installation.
3.
Install fuel tube and fuel injector assembly as follows:
CAUTION:
Do not let the tip of the injector nozzle come in contact with other parts.
a.
Insert the tip of each fuel injector into intake manifold.
b.
Tighten bolts in two steps in numerical order as shown.
4.
Connect harness connectors to fuel injectors.
5.
Install intake manifold. Refer to
EM-27, "Removal and Installation"
.
6.
Connect quick connector at the engine side as follows:
a.
Check the connection for foreign material and damage.
b.
Align center to insert quick connector straight into fuel tube.
NOTE:
The figure shows the engine side as an example.
• Insert quick connector to fuel tube until the top spool on fuel
tube is inserted completely and the second level spool is posi-
tioned slightly below quick connector bottom end.
CAUTION:
• Hold (A) position as shown when inserting fuel tube into
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.

(engine side)
• Install so that the arrow mark on the side faces up.
CAUTION:
• Make sure that quick connector and fuel tube are securely
fit into quick connector cap installation groove.
• If quick connector cap cannot be installed smoothly,
quick connector may have not been installed correctly.
Check the connection again.

Apply fuel pressure to fuel lines by turning ignition switch ON (with the engine stopped). Then check for
fuel leaks at the connections.
2.
Start the engine and rev it up and check for fuel leaks at the connections.
