I am installing the Dynon supplied fuel pressure sensor on my ES power by IO550n19B and the Dynon documentation indicates that the connection should be thru a restricted fitting.  The oil pressure sensor has the same note and Lancair supplied a HK822-4 adapter that was restricted for the oil.

Unfortunately the fuel pressure pick up comes off a T (with ¼ flare tube)and neither port on the T is restricted.  Obviously the HK822-4 won’t work there as it is 1/8 pipe to ¼ tube.  Would appreciate any insight how others have accomplished this connection.
