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 stiffening 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 diameter 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. Ap-
ply 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.
