D. Thread the supplied plug with an O-ring into
the front of the fuel rail. Thread the 1/4" NPTF
O-ring adapter fitting into the rear of the fuel
rail. Use light oil on the O-rings.
Do not over-
tighten fittings. Thread the 1/4" NPT x 90
°
fitting into the installed adapter fitting at the
rear of the fuel rail (use a small amount of
Teflon paste on the pipe threads only. Do not
get any paste on the inside of the fuel rail).
Rotate the 90
°
fitting so that the flare portion
points down toward the valve cover.
E. Attach the previously installed braided hose to
the 90
°
fitting on the rail. Make sure that the
hose is not twisted after the hose has been
tightened.
F. From the engine compartment, remove (pull
out) the grommet in the firewall that surrounds
the transmission gear select cable. Use a
razor blade to carefully slit the grommet and
temporarily remove it from the cable.
G. Cut the center of the grommet out to make
room for the vacuum line and harness that
must attach to the Vortech SFIC which will be
located under the dash (see
Figure 13A-d ).
H. Mount the Vortech SFIC unit inside the panel
beneath the steering column with the Velcro
strips and adhesive pads provided (see
Fig-
ures 13A-b, 13A-c ).
I. Using the supplied 5/32" TEE, tap into the
previously installed ignition vacuum line. Con-
nect the wires and vacuum line for the SFIC.
Attach the black wire to
ground. Connect the red
wire to the interior fuse
panel cavity #3 (ABS) with
the special mini fuse tap
and female connector pro-
vided. Route the brown
wire, two injector har-
nesses and vacuum line
out into the engine com-
partment. Connect the
brown wire to the negative
wire going to the coil (white
wire to the Crane ignition
box). Attach the two injec-
tor harnesses to the
supplementary injectors
(plugs are interchangeable
and reversible). Connect
the vacuum line to the
manifold (TEE into the by-
pass valve hose).
