disconnect ground cables from both batteries.
Remove the air filter, housing, intake silencer
and flexible duct, from the engine and inner fender
panel. cover the intake manifold opening with a clean
rag to prevent foreign objects from entering the intake
manifold.
adjust the injector pump. refer to the injeCTiOn
PUMP aDjUsTMenT section at the back of these
instructions. When the pump adjustment is completed,
make sure that the ground cables from both batteries
are disconnected, then continue with the following
steps.
Remove anti-depression valve (cdR) and hose
from right hand valve cover and intake mani-
fold. Re-install the valve but not the 1” rubber hose.
Install 1” dia. rubber cap over fitting on intake manifold
where hose was removed. use a no. 16 hose clamp,
provided, to secure the cap. see figure 3.
Remove and discard air inlet gasket from the intake
manifold. Remove air filter mounting studs.
A. EGR EQUIPPED MODELS ONLY: Install two
pressure chamber mounting studs, provided, to
replace studs removed in the previous step. nOTe: One
end of stud has metric threads, this end threads into
intake manifold, through the egR valve.
nOn egR MOdeLs OnLY: Install two new pressure
chamber studs with two 5 ⁄
16
” thick spacers between
studs and intake manifold. spacers are included in the
Banks Heavy duty emissions Kit (ordered separately,
part no. 21058). see figure 3.
B. NON EGR MODELS ONLY: Go to Part C.
EGR EQUIPPED MODELS ONLY: drill a
21 ⁄
64
” hole in
the pressure chamber casting in the location shown in
figure 4. nOTe: drill bit is provided in the Banks Light
duty emissions Kit (ordered separately, part no. 21056)
IMPORTANT: Remove all burrs from the drilled hole
and all chips from inside the pressure chamber. clean
and dry the area around the hole inside the pressure
chamber.
Push one end of the blue silicone hose through the
drilled hole in the pressure chamber until half its length
(6 inches) is inside the pressure chamber. Once this
hose is started through the hole, it will be easier to
reach inside the pressure chamber to pull it through.
When the hose is in position through the hole, run
a bead of silicone sealant around the hose where it
enters the inside of the pressure chamber.
C. Install new air inlet gasket provided on the intake mani-
fold.
D. EGR EQUIPPED MODELS ONLY: Push the inner half
of the blue silicone hose over the nipple on top of the
egR valve. (Remove any hose clamps previously used
on the nipple). see figure 5.

” nPT pipe
plug in the left rear corner of the pressure chamber.
(Omit the pipe plug if a boost gauge is to be installed.)
see figure 3.
Raise the vehicle and support it on jack stands.
disconnect and remove exhaust pipes. Remove
