5. OIL FEED LINE

A. The supercharger uses engine oil for

lubrication and must have an oil feed line
connected to a filtered oil access on the
engine and an oil return or drain. The return
is a gravity drain and should be routed so a
gradual drop is provided and connected to
the pan above oil level and away from
suspension components or exhaust headers
or pipes.

B. Locate the oil pressure sender which is just

above the oil filter assembly. (See

Figure:

5-a

.) (1995-97 models have the oil sending

unit located in a different position.)

C. Unplug the sender wiring harness.
D. Using a 1-1/16" oil pressure sender socket,

remove the unit from the block.

E. Preassemble the 3" x 1/4" NPT nipple, 1/4"

NPT TEE as shown and install into the
sender port of the block. (See

Figure: 5-b

For 1995-97 models, remove the 1/4" NPT
pipe plug above the oil filter and install the
3" x 1/4" NPT nipple, 1/4" NPT female elbow
and #4 x 1/4" NPT straight fitting into the
block using engine oil on the threads for
lubrication.

Reassemble the mounting fitting and oil

sender using engine oil on the pipe threads.
Teflon tape, paste or other sealant is not
recommended as it might loosen and cause
blockage of the oil feed orifice, resulting in
supercharger failure.

WARNING: The oil system contains a small

NOT USE any type sealant on
any of the threads. Instead use
clean engine oil. Disassemble
and blow out the entire line if you
have any doubts.

NOTE: For 1995-97 models, skip steps C

and D.
