FITTING YOUR FPR
Locate fuel pressure feed line, base
pressure and determine mounting
location
1
CAUTION!
Ensure correct installation of fittings to prevent high
pressure and temperature fuel leaks which can lead
to extremely dangerous fires. See across for
example of ORB fitting – note the O-ring.
This line is usually found by identifying your
carburettor, the standard OEM Fuel pressure
regulator will be mounted to a return line or feed line
to the carburettor. Turbosmart recommends
determining your current base fuel pressure with
your existing regulator to identify a reference for the
base pressure you set the new regulator to. This can
be done with any reputable pressure gauge at idle
and with the vacuum hose disconnected from the
regulator. Take time to determine where you wish to
mount the FPR in the engine bay. Some examples of
placement for your FPR are:
•
•
•
Mounted against chassis
Mounted onto/near carburettor
Mounted onto intake manifold
CAUTION!
Do not place the FPR near a significant heat
source as this may lead to severe engine fires.
CAUTION!
Ensure to relieve fuel pressure before removing

Prior to mounting the FPR, install fittings into FPR
with high quality AN ORB fittings ensuring the O-Ring
is present. Optional Turbosmart fitting kits available
–
TS-0402-11XX (NPT, -6 to -10 AN)
CAUTION!
Flare fittings CANNOT be used internally on the
FPR. They must be ORB internally.
Fit Gauge or Sensor Port (OPTIONAL)

CAUTION!
This step is optional. Prior to mounting the FPR,
install 1/8” NPT gauge or sensor. Unscrew existing
1/8” NPT blank anti-clockwise with 3/16” hex key.
Apply thread lubricant and screw in clockwise until
finger tight, then tighten further 1-2 turns for seal.
Turbosmart gauge kit optional – TS-0402-2023.
O rings are not used in the FPR Kompact (1/8”
NPT) due to the tapered thread. A fuel safe thread
lubricant should be used.
