5. OIL FEED LINE cont'd.
G. Attach one end of the feed hose assembly
to the 90
°
flare previously mounted in the
block. Route the line around the oil filter
mount, along the oil cooler tubing and out to
the front of the engine block. Take care to
tie wrap and protect the line from kinking,
abrasion and high heat areas. (See
Figure
5-c
.)
H. Temporarily cover the end of the hose and
protect it from dirt until connecting to the
supercharger.

6. OIL DRAIN LIN E
A. To provide an oil drain for the supercharger,
it is necessary to make a hole in the oil pan.
Locate and mark hole. (See
Figures 6-a,
6-b
.). It is best to punch the hole rather than
drill.
B. Remove paint around the hole area.
C. Use a small center punch to perforate the
pan and expand hole, switch to a larger
diameter punch and expand the hole further
to approximately 9/16" diameter. Most
punches are made from hexagon material
and may be placed in a socket with an
extension to make this procedure easier.
Use caution so that the hole is not enlarged
too much and punch does not contact the
crankshaft.
D. Tap the hole with a 3/8" NPT tap
approximately 1/4" deep. Pack the flutes of
the tap with heavy grease to hold chips. Use
a small magnet to check for any stray 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
hose fitting and secure in hole. Make sure a
seal is formed all around the fitting.
F.
Drain the engine oil, install a new filter and
refill with fresh oil.

NOTE: This method of rolling over the lip of
the hole and tapping it works very well
if carefully done and should cause no
problems.
