A. Place the supplied air injection adapter into the
driver’s side exhaust air injection manifold port
with the taper facing up (if the exhaust manifold
is machined with an inverted flare seat for the
air injection flare fitting, ignore this point). See
Air Injection Modification diagram. If the
threads in the manifold are unusually deep
(such as in some aftermarket exhausts), use
the supplied washers to “space” up the adapter.
B. Thread the supplied tube nut and 5/8” flared
tube into the factory exhaust manifold injection
port.
