INSTALLATION

1. INSTALL INJECTORS AND DELIVERY PIPES

NOTICE:
- Be careful not to drop the injectors when installing the delivery pipes.
- Pay attention to put any hung load on the injector to and from the side direction.





(a) Install a new grommet and new insulator to each injector.
(b) Apply a light coat of gasoline to 2 new O-rings and install them to each injector.





(c) While turning the injector clockwise and counterclockwise push it to the delivery pipes. Install the 8 injectors.

HINT: Install the injector with cover for No. 5 6, 7 and 8 cylinders.

(d) Position injector connector outward.





(e) Place the 4 spacers on the intake manifold.
(f) Place the 8 injectors and 2 delivery pipes assembly in position on the intake manifold.





(g) Temporarily install the 4 nuts.





(h) Check that the injectors rotate smoothly.

HINT: If injectors do not rotate smoothly, the probable cause is incorrect installation of O-rings. Replace the O-rings.

(i) Position injector connector outward.
(j) Tighten the 4 nuts holding the delivery pipes to the intake manifold.
