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 mark the hole. (See

Fig. 3-a.)

This hole should be centered 7/16” from the
bottom of the oil pan lip and 5/8” from the left-
most edge of the oil pan.

B. Drill an 1/8” pilot hole at the center location.
C. Use a 9/16” roto broach to drill a hole in oil pan.

Break through the pan gently, so the cut out
piece does not go into the oil pan.

D. Tap the hole with a 3/8” NPT tap to approxi-

mately 1/2” deep or until fitting can be started.
Pack the flutes of the tap with heavy grease to
hold chips.

Thoroughly clean the threaded area. Reach in-

side the oil pan and retrieve any stray chips.
Apply a small amount of silicone sealer to the
new threads. Apply more sealer to the supplied
3/8” NPT nipple and secure it in the hole. Make
sure a seal is formed all around the fitting.
Thread the supplied 3/8” NPTF x 1/2 flare fitting
onto the nipple. (See

Fig. 3-b, 3-d.)

Install the supplied oil drain tube assembly onto

the flare fitting. Before tightening the tube nut on
the drain tube, angle the tube slightly upward at
the open end so the oil will drain “downhill” into
the pan.(See

Fig. 3-c.)

G. Temporarily cover the oil drain tube end to keep

any debris out.

H. Drain the engine oil, install a new filter and refill

the engine with fresh oil.
