Control Pressure Regulator Readings 200

Hi, I finally got the fuel pressure gauge to test my 0 438 140 128 CPR on my 85 240ti. (1)Tested system pressure 84 cold. (2)Control pressure (60)cold. (3) Control pressure (63)warm. (4) Residual pressure after 20 min.(36). So from what I have read the cold control pressure reading may mean the CPR has a possible clogged filter.Any input is welcome. At this point I'm not willing to pull it apart until I have a spare one. Anyone have one they want to part with? Charlie
