A. To provide an oil drain for the supercharger, it
is necessary to make a hole in the front of the
oil pan. Locate and center punch the hole per
Fig. 3-a. This hole should be 3/4" from bottom
of oil pan lip and centered between the stiffen-
ing ribs.
B. Remove the paint around the hole.
C. Use a small center punch to perforate the pan
and expand the hole. Switch to a larger diam-
eter punch and expand the hole further to
approximately Ø9/16".
D. Tap the hole with a 3/8" NPT to approximately
1/2" deep or until the supplied drain fitting can
be started. Pack the flutes of the tap with
heavy grease to hold chips.
E. Thoroughly clean the threaded area. Apply a
small amount of silicone sealer to the new
threads. Apply more sealer to the 3/8" NPT x
1/2" inverted flare fitting and secure in the
hole. Make sure that a seal is formed all
around the fitting.
F. Thread the tube nut and 1/2" aluminum tube
into the inverted flare fitting by hand. Do not
tighten until the supercharger drain hose has
been connected.
G. Temporarily cover the end of the oil drain tube
to keep out debris.
H. Drain the engine oil and refill with fresh oil.

NOTE: This method of rolling over the lip of the
hole and tapping it works very well if care-
fully done and should cause no problems.
NOTE: Upon breaking through the oil pan, oil may
drain out of the newly formed hole. Some
oil may be drained from the pan if the oil
continues to flow.
