FITTING YOUR FPR
Locate fuel pressure feed line, base pressure
and determine mounting location
Fit Gauge or Sensor Port (OPTIONAL)
This line is usually found by identifying your injectors, the fuel rail This step is optional. Prior to mounting the FPR, install 1/8” NPT
the injectors are mounted to and then the line that is feeding the gauge or sensor. Unscrew existing 1/8” NPT blank anti-
fuel rail. Turbosmart recommends determining your current base clockwise with 3/16” hex key. Apply thread lubricant and screw
fuel pressure with your existing regulator to identify a reference in clockwise until finger tight, then tighten further 1-2 turns for

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 fuel rail
Mounted onto intake manifold
Do not place the FPR near a significant heat source as this may
lead to severe engine fires.
Prepare FPR for installation
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
Please note that O rings are not used in the FPR 800 due to
the tapered thread. A fuel safe thread lubricant should be
Mounting your FPR
With all fittings installed onto the FPR, the FPR can now be
mounted. Place the mounting bracket over the base of the FPR
in the orientation of your choice, place the circlip over the top of
the mounting bracket and with external circlip pliers expand the
circlip and push down until the circlip clicks into place. Your
mounting bracket is now successfully installed and you can now
mount your FPR in your specified location. Proceed to connect
your fuel lines.
Ensure correct installation of fittings to prevent high pressure and
temperature fuel leaks which can lead to extremely dangerous
fires. See below the O-ring.
Start engine and check for leaks
Congratulations, your FPR is installed and ready for use.
Double check all fittings, lines and mountings then proceed to
activate fuel pumps and check for leaks.
CAUTION! If fuel leaks are present – switch off engine
immediately and rectify leaks.
