It may be necessary to gently bend the air condition-
ing line to gain clearance between it and the super-
charger discharge.
C. Install the supplied 3/4" NPT x 90° brass fit-
ting into the lower threaded opening of the
aftercooler core; the fitting must face
towards the firewall of the vehicle. Install
the supplied 1/2" x 3/4" straight brass fitting
into the upper threaded opening in the after-
cooler core.

elbow hose onto the bung on the 180° air

duct. Install the supplied bypass valve into
the hose lines per Fig. 10-c.
E. Attach an end of the supplied 5/32" vacuum
hose onto the vacuum nipple on the previ-
ously installed bypass valve. Route the

booster mounted on the driver’s side firewall
and secure the hose as necessary using the
supplied wire ties.
F. Remove the small vacuum cap from the fac-
tory fitting on the vehicle’s brake booster.
Attach the supplied vacuum hose onto the
open port on the brake booster, install a sup-
plied 5/32" brass reducer into the vacuum
line previously installed. Trim the supplied
5/32" vacuum line connected to the bypass
valve for the best fitment and install onto the
open port of the previously installed reducer.
