Unhappy fuel pressure port on 2004 tj x jeep ?

cannot find a fuel pressure test port on my 2004 jeep its not on fuel rail like service manual shows not to sure how to pressure cheek ,think may have a bad regulator or clogged fuel filter but have no idea how i can check pressure.jeep struggles to get at 70 on highway ,intown good acceleration ,good flow trough exhaust ,main cat removed ,idles smooth ,doesn't miss,no codes ? I'm lost figure gotta be filter or regulated. any body got a solution to pressure testing or other possible solution to problem?

The pressure test ports on the fuel rails were discontinued prior to 2004.
