INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPES
NOTE:
- 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.
