A. Screw two 3/4" straight brass fitting into the
plastic surge tank. (See Fig. 16.B-e.)
B. Using the supplied 1/4-20 x .50 hardware and
washers attach the surge tank mounting
bracket to the surge tank. (See Fig. 16.B-e)
C. Unbolt the two bolts holding the passenger’s
side hood hinge brace at the base of the
windshield. Remove the plastic push-pin
between the two bolts.
D. Apply light pressure to drop the hood support
down and install the surge tank/bracket
assembly between the hood support bracket
and cowling while aligning the bracket and
push-pin holes. Using the stock hardware and
push-pin secure the bracket in place. (See

H. Place the water reservoir assembly under the
passenger’s side door with the short sides of
the triangular tank against the frame rail and
nerf bar support.

locations where you will need to drill. Use a
1/8" drill for the two locations on the frame
rail. Secure those two locations with the sup-
plied sheet metal screws. For the third loca-
tion on the nerf bar support, use a 9/32" drill
and secure with the supplied 1/4-20 x 1" bolt,
1/4" nut and washer. (See Fig. 16.B-g.)
