tion of the bracket. nOTe: Make sure the latches are
in a raised position before tightening nuts or latches
will not clear pressure chamber.
a. slide air filter into filter housing. The step on the
small end of the filter should extend about

the plastic housing to support and center the filter.
Push the filter all the way into the housing.
b. Position a no. 74 hose clamp over the neck of the air
filter. Place the rectangular projection on the bottom of
the filter housing through the corresponding opening
on the filter mounting bracket. slide the filter/housing
assembly rearward in the bracket while guiding the
turbo inlet elbow into the air filter neck until it stops.
now tighten the two no. 52 hose clamps at the turbo
and the intake elbow. Push the filter and filter housing
forward within the confines of the slot in the air filter
bracket, then latch the filter housing in place. Make
sure the front end of the filter projects

filter housing. now tighten the filter bracket bolts and
the no. 74 hose clamp at the filter neck.
NOTE: On air conditioned models, one refrigerant hose
passes over the air inlet elbow. To prevent this hose
from putting undue pressure on the air filter neck or
rubbing on the air inlet elbow, it can be lifted some-
what by one of the following methods. If the hose does
not rub on the air inlet elbow, proceed to Step 20.
On models with a threaded hose connection
at the air conditioning compressor, carefully
loosen the nut on the hose connection just enough to
rotate the hose into a more desirable position provid-
ing additional clearance. This can usually be accom-
plished without the loss of any refrigerant. Tighten the
nut when complete. On models where the hose termi-
nates into a bent steel tube section and is bolted to the
compressor, carefully bend the steel tube section up
slightly to raise the hose. slide the factory protective
sleeve on the hose to a position adjacent to the wind-
shield wiper motor, then tie the hose to the motor with
a cable tie wrap to pull the hose up and away from the
inlet elbow. see Figure
20,21.
On late model vehicles where engine intake air is
drawn through a plastic duct from over the grille, the
duct must be cut just where it begins the last bend,
see Figure
22
. some early model vehicles where duct
comes from below battery may require similar modifi-
cations if inlet hose kinks.
a. install the factory flexible air inlet hose between the
air filter housing and factory air inlet duct. Check that
brake line tube from master cylinder does not rub on
flex hose. Carefully bend tube if required. nOTe: On
late model vehicles where engine intake air is drawn
over the grille, trim the padding away from the under-
side of the hood above the air inlet as shown in Figure
23.
This prevents the padding from being sucked up
against the air intake and blocking air flow.
install the factory oil pressure sender in the oil
inlet block on the turbocharger. Use teflon tape
on the threads. On early model vehicles which use the
large diameter pressure sender, install a 45° brass street
elbow between the turbo and the sender to clear the
turbo. When sender is installed, reconnect sender wire
from wire loom. Make sure wire is routed away from hot
turbo surfaces. see Figure
18.
a. Connect the turbo oil feed hose to the elbow on the
turbo center section.
