Many motorhomes are manufactured with the under-
side of the floor so close to the top of the radiator
that the GM air inlet duct cannot be used. for these
applications we have supplied additional 4” diameter
flex hose that may be slightly flattened to fit between
the radiator and the floor, provided the hose is as
least 2 1 ⁄
4
” high after flattening. the plastic bulkhead
fitting may be used as a coupling to join the two flex
hoses together using two no. 64 hose clamps.
if your installation requires this procedure, substitute
the instructions on this sheet for steps 5 thru 9 of the
installation procedure. See Figure 4.
insert the banks plastic bulkhead fitting
through the bracket from the back side. the
bulkhead fitting may be used as is, or the curved por-
tion may be cut off if this lines up better with the fac-
tory air inlet duct. Figure 5 shows where to cut the
bulkhead if the curved portion is to be removed.
drill four 3 ⁄
16
” diameter holes through the air
inlet hood bracket around the perimeter of
the center hole. See Figure 6 . if the bracket
cannot be drilled while in place, it may be unbolted
for drilling.
Slip the bulkhead fitting into the end of the
factory air intake duct, and rotate the bulk-
head fitting into the desired mounting position.
have someone hold the bulkhead fitting against the
mounting bracket from the back side while you mark
the centers of the four drilled hole locations. drill four
1 ⁄
16
” diameter holes into the bulkhead fitting at these
points.
now bolt the bulkhead fitting to the bracket
using four no. 6 x 1 ⁄
2
” sheet metal screws.
hook up the factory flex hose from the air filter base
to the bulkhead fitting.

determine a location for the banks Super-
Scoop™. it should be placed as low as possible
directly behind the grille, with the air inlet opening
pointing straight ahead. if the grille is at an angle, the
Super-Scoop should be trimmed at an angle to place
the air inlet opening against the back side of the grille
with the centerline of the inlet opening horizontal.
See Figure 7 . use heavy snips or a hack saw to trim
the air inlet opening of the Super-Scoop.
