Banks Power GM Motorhomes: (Gas ’96 - 00 7.4L Vortec) Power Systems- Stinger system (Carbureted, P30 chassis) - Manual (Page 4)

have provided three universal tailpipe hangers
that may be attached to crossmembers, frame
rails, etc. with the remaining 3 ⁄
8
–16 x 1” hex bolts,
nuts, and washers. See Figure 1 for tailpipe
assembly. Maintain 1 1 ⁄
2
” of clearance to frame and
body to prevent rattles and hot spots.
Install the chrome tailpipe extension tip (Figure
1, #11). extension tip may be slid in or out over
tailpipe until desired length is obtained for body
width. Then clamp extension to tailpipe using 3”
u-clamp. NOTE: If tailpipe passes under any side
compartments or within proximity of floor (4-6”),
we highly recommend the installation of a tailpipe
heatshield (optional, available from Banks) to
prevent burning of carpet and other combustibles.

lower the vehicle and reconnect the battery
cables. start engine and listen for any
exhaust leaks. Tighten bolts or clamps to correct
leaks as required. NOTE: The vehicle exhaust may
smoke upon initial start-up. This is normal, as
grease used in the tube-bending process burns off
the pipes.
If a Banks Ram-Air intake system is not
being installed with the stinger, the installation
is complete and the vehicle may be test driven
(listen for any rattles or exhaust leaks that may
require attention). If a ram-air intake system is
being installed, complete the ram-air installation
and then test drive the vehicle.

RAm-AIR INSTALLATION PROCEDURE
The Banks Ram-Air cold air induction components
are designed to extend the factory air intake
path so the cooler outside air can be picked up
from directly behind the vehicle’s grille. These
components include a molded Ram-Air inductor
(Figure 1, #A ), 4” diameter flexible tubing (Figure
1, #C ), a molded bulkhead fitting (Figure 1, #D ),
and installation hardware. Figure 2 shows a
typical hook-up of the air intake components
as they tie to the factory system. The ram-air
inductor also serves as a water separator to drain
out any rain water that may enter through the
grille.
The Banks Stinger cold air induction package is
intended to fit a number of motorhome body
configurations. because each coach builder has a
different layout of behind-the-grille components,
there can be no one set installation procedure for
the banks air induction package. The following
instructions are intended as a guideline for
installing the air induction system. also, some
coach builders may have installed difficult to
relocate components (such as air conditioning
freon piping) in the areas where the banks
induction system is normally mounted. In these
cases, the installer will have to find an alternative
location for the induction components, or omit
those pieces that are impossible to ount.
Install the foam gasket strip in the groove
around the outside edge of the air filter
cover casting. Peal the paper off the gasket to
expose the adhesive. Trim the ends square with
a knife or razor blade to form a tight junction. do
not stretch the gasket as you instait.
remove the air filter cover and filter
element. clean any oil or debris from the
inside of the air filter base. Install the air filter
element and air filter cover casting (Figure 1,
#E-F ). If your original air filter cover has tune-up
and emissions specifications on it, save it for
future refernce.
Determine a path for the inlet air ducting
from the air filter base forward to the
vehicle’s grille. some vehicles have a plastic air
inlet duct attached to the snorkel on the base of
the air filter. This duct typically draws air through
a plastic air inlet hood that is mounted either
above, or to one side of the radiator. If this duct
and hood are in place, proceed to step 4. If not,
skip steps 4 through 8 and proceed to sep 9.
Disconnect the plastic factory air inlet duct
at the air inlet hood. remove the air inlet
hood from the mounting bracket by twisting it
until the four tabs line up with the slots in the
bracket. See Figure 5.
Insert the Banks plastic bulkhead fitting
(Figure 1, #D ) through the bracket from the
back side. The bulkhead fitting may be used as is,
or the curved portion may be cut off if this lines
up better with the factory air inlet duct. Figure
6 shows where to cut the bulkhead if the curved
portion is to be reoved.
