11. IDLE AIR CONTROL RESONATOR AND CRANKCASE VENT HOSE REROUTING
14
A. Attach the supplied 3/4” x 90° rubber elbow to the
idle control motor near the throttle body. (See
Fig.
11-a
.) Insert the factory idle control resonator into
the elbow and locate underneath the discharge tube.
B. Connect the supplied 3/4” x 28" hose to the idle con-
trol resonator and route the remaining end to the new
air inlet location. See step 14.
C. Remove the 90° rubber elbow from the factory valve
cover vent on the left side of the engine. Attach the
short leg of the supplied 5/8" x 90° x 24" hose to the
valve cover and route the long straight end over to
the brass fitting on the supercharger inlet elbow. Trim
hose length, if necessary. See step 14.
12. SUPERCHARGER MOUNTING
A. Attach the oil drain hose to the oil drain fitting on the
bottom of the supercharger and secure with the pro-
vided #8 hose clamp.
B. Guide the oil drain hose over the driver's side valve
cover while placing the supercharger in the appropri-
ate location. (See
Fig. 12-a
.)
C. With the oil drain hose properly routed downward,
start the five 3/8-16 x 2-1/2” counter sink bolts and
tighten evenly.
E. Using a few drops of engine oil on the fitting threads,
install the 1/8” NPT x -4 x 90° fitting into the super-
charger oil feed. Rotate the fitting toward the front of
the vehicle. Use a 1/2” wrench to hold the supercharger
oil feed while tightening the brass 90° fitting.
F. Two oil feed hoses have been supplied. The 36" long
hose is for use on the 2WD models that are not
equipped with an engine oil cooler. The 62" hose is
for use on 4WD oil cooler equipped models. Connect
the proper length oil feed line to the vehicle and se-
cure both ends. Make sure that no dirt or debris en-
ters the oil hose while routing to the feed fittings.
5.4L ONLY - Once the oil drain hose has been prop-
erly routed downward, use the five 3/8-16 bolts and
washers, start and tighten evenly.
D. Route the oil drain hose around the side of the power
steering pump and to the oil drain fitting on the oil
pan.

NOTE: The oil drain line must be routed in a
downward sloping fashion with no kinks
or restrictions.
NOTE: Do NOT use any type of sealant on the
oil feed fittings. It may become dis-
lodged and clog the oil feed orifice,
causing premature failure of the super-
charger.
