2.
Determine a location in the engine compartment to mount the fuel
pressure regulator. Make sure it is close enough to the factory steel
return line that you will have enough -6AN hose to reach from the
fuel filter to the fuel rail and from the fuel rail to the regulator. We
chose a location on the firewall.
3.
To mount the regulator in this location you will need to remove the
cowl cover (See Fig 3) .
Figure 3 - Cowl Cover Removed
4.
Following the instructions provided with the fuel pressure regulator,
use the provided bracket, and mark the location to drill the mounting
holes.
5.
Using appropriate hardware (sheet metal screws, or bolts & nuts
available through your local hardware or auto parts store), mount the
fuel pressure regulator to the bracket, and the regulator/bracket
assembly to the firewall (See Fig. 4) .
NOTE: You may need to bend/modify the supplied bracket in
order to mount the fuel pressure regulator in your desired
location.

Install the factory fuel pressure regulator vacuum line onto the fitting
on the fuel pressure regulator. You may need to replace or extend
this line, depending on where you are mounting the regulator.
FUEL LINE AND HOSE END PREPARATION:
1.
Measure the -6AN hose and determine the lengths needed to reach
from the fuel filter to the fuel rail and from the fuel rail to the fuel
pressure regulator. Mark the location to be cut and wrap the hose
tightly with masking or electrical tape at this point. Make sure to
use enough hose to prevent the possibility of the hose kinking after
assembly.
2.
Clamp the hose loosely and position the cut line at the edge of the
vice. The best way to cut is with cutting wheel or a hacksaw with
two blades opposing one another. Remove the tape when you are
finished cutting. Proclassic hose may be cut using a utility knife.
3.
Locate the hose ends to be used in your installation. For the fuel
filter to fuel rail supply line, use one -6AN straight hose end at each
end of the line. For the fuel rail to fuel pressure regulator line, use
one 45° swivel hose end and one 90° swivel hose end.
NOTE: The instructions here describe the hose end locations
used for our particular installation. You may use the supplied
hose ends in any location necessary for your configuration.
4.
Hose End Assembly:
NOTE: Use fitting assembly lube when assembling hose ends.
Use AN wrenches if available, and DO NOT OVERTIGHTEN
FITTINGS. See Russell catalog or contact the Edelbrock Tech
Line for details.
A.
Unscrew the socket of the hose end from the nipple. Hold
the socket carefully in a vice using soft jaws and insert the
hose into the socket by turning it counter-clockwise. The
hose will stop at the bottom step of the socket.
B. Position the nipple assembly of the hose end in the vice
using soft jaws. Apply assembly lube to the threads of the
socket as well as to the nipple assembly.
C. Start the socket over the nipple by hand to ensure correct
alignment of threads and tighten as far as possible by
hand. Finish with the correct AN wrench until it reaches
the nipple hex or when there is no more than 1/16" gap
between the nipple/socket assembly. Be sure to wash and
pressure test the assembly before using.
