C. Using a spring-lock fitting disconnect tool,

disconnect the return line (the line closest
to the front of the car) from the fuel rail (at
the top rear of the intake manifold).

D. Install the supplied 45" fuel line by

connecting the female spring-lock end
onto the fuel rail. Run the line parallel to
the feed line and then downward behind
the wheel well to the FMU. The flare end
will be connected to the 90

inlet fitting on

the FMU.

E. Fit the 28" male fuel line into the braided

tank return line. Route the braided tank
return line assembly forward to form a
smooth radius pointing downward. Use
tie wraps to hold the line in position.
Route the flared end of the line downward
behind the wheel well with the other FMU
line to the FMU. Connect the line to the
center fitting.
