Typical Installation
1.
Once the engine has been allowed to cool, disconnect the negative battery cable and
relieve the fuel system pressure. Refer to your vehicles manual to do this.
2.
Remove the old fuel pressure regulator and remove its vacuum line (some vehicles do
not have vacuum operated regulators).
3.
Place a container around the regulator to catch any fuel that is spilled during the
removal of the old regulator.
4.
Mount the regulator in a suitable place in the vehicles engine bay using the supplied
mounting bracket and self tapping screws, or an equivalent safe method (other
brackets may be used if necessary).
5.
Attach the fuel supply line to the -10AN inlet port on the front of the regulator using AN
ORB style fittings and o-rings. Attach
the carburetter’s supply lines to the
-06AN outlet
ports. Install the appropriate -06AN plug if only one outlet is being used.
6.
Attach the fuel return line to the regulators bottom port using an -08AN ORB style
fitting.
7.
Make sure to tighten all connections to prevent any leaks before adjusting the fuel
pressure.
8.
Once the regulator is installed, attach a suitable fuel pressure gauge to one of the 1/8”
NPT ports on the fuel pressure regulator (PFEFG15BK). Use thread sealant when
installing the fuel pressure guage and ensure the other port is blocked.
9.
Ensure that the area around the engine bay is free from any fuel including under and
around the vehicle.
10.
Reconnect the battery and turn the ignition to the on position without starting the car.
After several seconds, check the fuel pressure. If there is no fuel pressure, turn the
ignition key to the OFF position, wait one minute, return the ignition to the ON position,
and recheck the fuel pressure. Repeat this ignition OFF and ON procedure until the fuel
pressure gauge registers fuel pressure.
11.
Once the fuel pressure gauge registers fuel pressure and there are no fuel leaks, start
the engine and adjust the regulator to the desired fuel pressure. Turning the
adjustment screw CLOCKWISE will increase fuel pressure. The fuel pressure
adjustment range for the enclosed regulator is 4-13 PSI.
12.
Once the desired fuel pressure is achieved, tighten the regulator adjustment jam nut
and attach the vacuum line if the vehicle has one. If the vehicle is not equipped with a
vacuum line, leave this vacuum port open to atmosphere. Blocking the vacuum port
will yield poor regulator performance.
13.
If you do not want to keep the fuel pressure gauge on the vehicle, relieve the fuel
system pressure as instructed in the appropriate vehicle service manual. Remove the
fuel pressure gauge and reinstall the 1/8
”
NPT plug into the regulator gauge port, using
thread sealant.
