Install the two fittings into the end of the air
filter and re-install onto the supercharger inlet
and secure. (See Fig. 7-a.)

Locate the pressure solenoid removed from
the plastic air filter enclosure in a previous
step.

Secure the solenoid to the top of the passen-
ger’s side frame rail using the factory retainer
as shown. (See Fig. 7-b.)

Using the supplied union and length of
Ø5/16" hose provided, connect the formed
rubber hose (previously connected between
the filter enclosure and the solenoid

) to the

vacuum port as shown. (See Figs. 7-b, 7-c.)

Connect the remaining portion of the Ø5/16"
hose between the Ø5/16" x 90° fitting previ-
ously installed into the air filter and open vac-
uum port on the pressure solenoid. (See
Figs. 7-a, 7-b

NOTE:

Thoroughly clean the inside of the filter
and inspect to make sure no material is
left from the drilling process.
