INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPES
NOTICE:

Be careful not to drop the injectors when installing
the delivery pipes.

Do not apply any load to the injector on horizontal
direction.
(a) Install a new grommet to each injector.
(b) Apply a light coat of gasoline to a new O±ring and install
it to each injector.
(c) While turning the injector clockwise and counterclock-
wise, push it to the delivery pipes. Install the 8 injectors.
(d) Position the injector connector outward.
(e) Place the 8 new insulators on the intake manifold.
(f) Place the 2 delivery pipes and injectors assemblies on the
lower intake manifold.
(g) Temporarily install the 4 nuts.
(h) Install the front fuel pipe with the bolt, 4 new gaskets and
2 union bolts.
Torque:
39 N´m (400 kgf´cm, 29 ft´lbf) for union bolts
7.5 N´m (76 kgf´cm, 66 in.´lbf) for bolt
(i) Install the bolt holding the clamp on the fuel return pipe to
the LH delivery pipe.
Torque: 7.5 N´m (76 kgf´cm, 66 in.´lbf)
(j) Check that the injectors rotate smoothly.
HINT:
If the injectors do not rotate smoothly, the probable cause is in-
correct installation of O±rings. Replace the O±ring of the injec-
tor that does not rotate smoothly.
(k) Position injector connector outward.
(l) Tighten the 4 nuts holding the delivery pipes to the lower
intake manifold.
Torque: 21 N´m (214 kgf´cm, 15 ft´lbf)
