FUEL RAIL ADAPTORS:
Fuel rail adaptors are designed for connection of your FPR to your fuel system when your standard regulator is mounted on the fuel rail.
With the standard regulator removed, install a fuel rail adaptor in place of the stock regulator and use EFI fuel hose to connect to your
remotely mounted FPR.

FITTING!INSTRUCTIONS:!
1. Determine your current Base fuel
pressure.
Turbosmart recommends determining your current base fuel
pressure with your existing regulator. This should be done
prior to installation of the FPR to give a reference base
pressure to initially tune the base pressure to. This base
pressure measurement should be made with a suitable fuel
pressure gauge at idle with the vacuum hose removed.
Ensure the vacuum hose has been removed and is blocked
when taking the reading and the reference nipple is left
open to atmosphere.
2. Prepare to remove your existing regulator
Your fuel system is under pressure. To relieve the pressure
disconnect your fuel pump power or remove the fuel pump
fuse. Crank the engine until it stops. Your fuel system should
now have no stored pressure.
WARNING! Exercise extreme caution when
loosening fuel fittings. Turbosmart recommends
wearing safety glasses to protect against fuel
spray and having an appropriate fire
extinguisher on hand.
3. Remove your existing regulator
With your engine cool and ignition off you can now carefully
remove the fuel lines to and from you existing regulator.
You should take care with these lines to ensure no debris
enters your fuel system.
Disconnect the vacuum line and remove the existing
regulator.
IMPORTANT NOTE:
If your standard fuel pressure regulator is mounted directly
to your fuel rail then you may need to use an adaptor and
some EFI fuel hose to connect the fuel rail to the FPR inlet
port. Turbosmart supplies a range of adaptors to suit most
popular makes and models (see accessory table for details).
4. Mount the FPR
Mount the FPR using the mounting bracket supplied. Ensure it is
firmly mounted and if necessary use the bracket as a template for
marking out new mounting holes. Use the spring washers
supplied when bolting the FPR to the bracket.
5. Connect Fuel Lines
Connect the fuel inlet and return lines in the orientation
shown. If only one inlet is used block the second inlet with
an blank.
6. Start engine and check for fuel leaks
Replace the Fuel pump fuse or reconnect the fuel
pump power. Start your engine and check for fuel
leaks around the fittings.
CAUTION! If any leaks are evident turn the
engine of immediately and tighten fittings
and re-check until no leaks are present
before proceeding.
WARNING! No Smoking or Naked flames in
the vicinity of this installation.
