Locate the small metal breather tube
pressed into the bottom of the cast

the metal piece leaving an open hole.
Use a 7/16" drill to enlarge the hole.

tion. Use a 9/16 rota-broach to drill a
hole in the manifold. (See Fig. 3-b.)
3. Tap the hole with a 3/8" NPT tap to
approximately 1/2" deep or until the fit-
ting can be started.
4. Apply a small amount of silicone sealer
to the supplied 3/8" x 45° street fitting
and secure it in the hole. Thread the
3/8" nipple into the street elbow. Orient
the elbow and nipple toward the dri-
ver’s side. (See Fig. 3-c.)
