11. FUEL MANAGEMENT UNIT INSTALLATION
A. Mount the fuel management unit (FMU) to
the firewall on the driver's side. Placement
should be on the flat area near the top of the
firewall just below the hood hinge base and
outward from the swinging portion of the
hood hinge. Use the sheet metal screws in
the kit to secure.
B. Using a special tool for
springlock connec-
tors, disconnect the stock fuel return line
where it exits the stock fuel pressure regula-
tor near the fuel rail.
C. Snap the Vortech fuel line with the male
springlock connector into the regulator out-
let. Attach the other end to the Vortech fuel
management unit inlet. Route the line over
the brake booster and through the existing
clamps.
D. Snap the second line with the female
springlock connector onto the fuel return line
that was connected to the regulator outlet.
Connect the other end to the FMU outlet at
the center fitting. Route this line along with
the first line.
E. Connect the 5/32" vacuum line from FMU to
intake manifold fitting and secure (see
Fig-
ures 11-a, 11-b, 11-c
).
F. Install the 3-1/2" flex hose between the air
filter and elbow and secure with hose clamps.
