FUEL PRESSURE REGULATOR MOUNTING:
Install the provided fittings into the fuel pressure regulator (See Fig.
1.
2) . Install one -6AN Dry Sump Union in the inlet port and one in the
return port (located at the bottom of the regulator). Install the -6AN
block off plug in the fuel outlet port of the regulator. Slip the -6AN
Female coupling nut over the -6AN female to -4AN male coupling.
Install this assembly over the -6AN dry-sump fitting previously
installed in the return port of the regulator. Install the vacuum fitting
supplied with the regulator in the port on the top half of the
regulator. Install the pressure adjusting screw and jam nut at the
top of the regulator. See the instructions provided with the regulator
for more information.
2.
Determine a location in the engine compartment to mount the fuel
pressure regulator. Make sure it is in a location that will provide
clearance to route the -4AN return line to the regulator, and that you
will be able to easily connect a length of -6AN hose between the fuel
rail and 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.
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.
