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.

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.

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.
