11. FUEL MANAGEMENT UNIT
A. Install the fuel management unit (FMU) on the
firewall outward from the brake booster and
below the hood hinge. Make sure to leave
clearance for the hinge.
B. Use a snaplock fitting tool to disconnect the fuel
return line from the fuel rail and snap in the FMU
inlet line. The inlet line runs to the outward fitting,
not the center fitting. (See
Fig. 11-a.)
C. Connect the FMU outlet line to the return line.
D. Secure both lines away from the exhaust header
and pipe and away from all moving parts. Check
that all fittings are secure.
E. Connect the 5/32" vacuum hose between the
FMU and the vacuum tree located on the front
portion of the intake manifold. (See
Fig. 11-b.)
