2. OIL FEED

Fig. 2-a

A. The supercharger uses engine oil for lubrication

and must have an oil feed line connected to a

filtered oil access on the engine.

B. Locate the oil pressure sending unit on the pas-

senger side of the engine, toward the front (see

Fig. 2-a

). Using a 7mm socket, remove the signal

wire from the sending unit. Using a 15/16 socket,

remove the sending unit from the engine.

C. Install the supplied 1/8" BSP adapter into the

block. Install the supplied 1/8" NPT street TEE

into the BSP adapter. Thread the stock sending

unit into the tee as shown in

Fig. 2-b

. Reattach

the stock signal wire and nut to the sending unit.

D. Install the supplied 90° x 1/8" NPT x #4 flare fitting

into the previously installed TEE. (See

Fig. 2-c.

)

Make sure that the fitting is tightened and clocked

as shown.

E. Temporarily cover the open fitting hole to keep

out debris until the connection is made to the

supercharger hose in step 12.

NOTE: Use only clean engine oil on the pipe

threads. Teflon tape or pipe sealant is not

recommended as it might loosen and cause

blockage of the small oil feed orifice result-

ing in possible supercharger failure.
