OIL DRAIN INSTALLATION
4.1 OIL dRAIN INSTALLATION (OPTION 1)
A. To provide an oil drain for the supercharger,
it is necessary to install the supplied
mechanical fuel pump block off plate with
barb fitting.
B. Install the plate and gasket using two sup-
plied 3/8-16 x .75” bolts and washers onto
the port located on the front passenger side
of the block, just behind the water pump.

C. Attach one end of the ½” drain line to the
barb end of the installed fitting and secure
with #8 hose clamp. Route the hose up
towards the passenger side of the car to be
connected to the supercharger in a later step.

4.2 OIL dRAIN INSTALLATION (OPTION 2)
A. Alternately, you can punch a hole in the side
of the oil pan. The hole should be placed
above the oil level in the pan to allow for
unrestricted flow of the return oil. (Roughly
no more than 1’” below the top edge of the
pan)
*** NOTE ***
Removal of the oil pan may ease oil drain fitting
installation on some applications.
B. Remove any paint from around the hole area.
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". 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 that the
punch does NOT contact the engine inter-
nals.
D. Tap the hole with a 3/8"NPT tap approxi-
mately 1/4" deep. Pack the flutes of the tap
with heavy grease to hold the chips. Use a
small magnet to check for any stray chips.

*** NOTE ***
This method of rolling over the lip of the hole and
tapping works very well if carefully done and should
cause no problems.
E. Thoroughly clean the threaded area. Apply a
small amount of silicone sealer to the new
threads. Apply more sealer to the supplied
3/8"NPT x 1/2" barb, and secure in the previ-
ously threaded 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.
