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.
