Fuel Pressure Sensor Connection

[tlwcfii]

From the installation manual: The fuel pressure sensor port has a 1/8-27 NPT pipe thread fitting; you may need adapters to connect to the pressure port on your engine. Locate the correct fuel pressure port for your engine. This port must have a pressure fitting with a restrictor hole in it. This restrictor hole ensures that, in the event of a sensor failure, fuel leakage rate is minimized, allowing time for an emergency landing.

I am connecting to a Flare 1/4" tube "T" on the IO550N which is not restricted.  Where can I find a connector fitting with the appropriate restriction?

Any help would be appreciated.

We're really only aware of the standard AN restrictors. You'll need to engineer something yourself or look around if you are trying to grab pressure from a non-standard location.

As an FYI, Vans sells the restrictors we are used to:
