Visually center the Banks snorkel
outlet adapter over the stock snorkel
outlet. Using the Banks snorkel outlet
adapter as a template, drill a 3 ⁄
16
”
hole into the snorkel through one of
the existing holes in the adapter. See
Figure 18.
23.
Temporarily insert a supplied
screw with a washer through the
Banks outlet adapter and intake
snorkel. Install another washer and nut
on the screw from inside the snorkel,
with the nut finger tight. Ensure both
pieces are still visually centered and
aligned with the mark made earlier,
then drill the remaining three holes
using the Banks snorkel outlet adapter
as the template. See Figure 19.
24.
Remove Banks outlet adapter and
set aside.
25.
With a felt marker or scribe, and
using the stock outlet adapter as a
center point, draw a circle 3 ⁄
16
” offset
from the stock outlet on the intake
snorkel. Using a utility knife, keyhole
saw, or similar, cut along the marked
circle to remove the stock outlet and
enlarge the opening. See Figure 20.
Note: The
3 ⁄
16
” offset is only a
reference dimension and is not critical.
Make sure that the new hole is at least
5” in diameter and does not break into
the Banks adapter mounting holes
drilled earlier. See Figure 21.
26.
After the hole has been cut and
the stock outlet fitting is removed,
debur all cut areas. Line up the screw
holes in the Banks snorkel outlet
adapter with the drilled holes in the
snorkel. Fasten them together using
the supplied screws (4), lock nuts (4),
and washers (8) (item 12,13,15). Each
screw should have a flat washer on
both sides of the joint.
27.
Locate the air box inlet hose (Item
18). Loosely fit two hose clamps (Item
17) onto the hose and install the hose
onto the modified inlet of the air box.
Tighten the clamp securing the hose to
the air box.
28.
If previously removed, install the
intake snorkel bracket and bolts onto
the frame and tighten.
29.
Install the intake snorkel outlet
into the hose inlet and then slip on
the snorkel strap and fasten to the
bracket. Tighten the clamp securing
the hose to the snorkel outlet. Tighten
the snorkel strap with the previously
removed bolt.
