A. The supercharger uses engine oil for lubrica-
tion 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
driver’s side of the engine, just in front of and
above the engine mount. (See Fig. 2-a.)
C. Disconnect and remove the pressure sender
and set aside to be re-installed later.
D. Locate the supplied oil feed assembly
(4LA130-026).
E. Install the supplied 1/8"BSP adapter into the
hole previously occupied by the oil pressure
sender. Install the supplied 1/8"NPT street
TEE into the BSP adapter. Orient the branch
of the TEE so that it faces up. Thread the fac-
tory sending unit into the TEE as shown.
(See Fig. 2-b.)

NOTE: The factory wiring harness may need to
be unclipped from the engine block to
gain the necessary length to reach the
repositioned sending unit.
NOTE: Pipe tape, paste or other sealant is not
recommended as it may loosen and
cause blockage of the oil feed orifice
resulting in supercharger failure. Use
engine oil on the threads.
F. Install the supplied 1/8"NPT x #4 flare fitting
into the previously installed TEE. (See Fig.
2-b.
)
G. Attach the straight end of the supplied oil feed
line to the #4 flare fitting previously installed
and route up and over the engine valve cover.
H. Temporarily cover the open oil feed line end
to keep out debris until the connection is
made to the supercharger in a later step.
I. Reconnect the factory oil pressure sender
wire.
