A. To provide an oil drain for the supercharger, it is
necessary to make a hole in the oil pan. Locate
and mark hole as per diagram. 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 the 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.
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
and thread in the oil drain assembly. 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 and change the filter.
4. FUEL MANAGEMENT UNIT
A. Disconnect the fuel rail return line behind the shock
tower and at the manifold fuel rail with spring lock
disconnect tool. Remove the fuel line. The return
line does not have a pressure test fitting on it. (It
is the smaller of the two lines).
B. Attach the supplied 14" fuel line to the center fitting
on the management unit (FMU). Mount the FMU
against the passenger side inner fender panel in
between the shock tower and the firewall using
sheet metal screws. Coil the units 14" return line
upward, forming a loop back down to the stock
return line. (See Fig. 4-a.)
C. Connect the FMU input hose from the fitting on
the side of the FMU to the return line coming from
the fuel rail regulator fitting as shown in Figs. 4-b,
4-c on the following page.
D. Using the stock hose mount on the shock tower,
secure the fuel lines away from the exhaust mani-
fold with the tie wraps provided.
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.
