Is there any adjusting the Fuel Pressure Regulator on a 305 w/TPI? Thanks for any help with this

 

I think you need an "adjustable fuel pressure regulator (AFPR)." I'm not totally sure but I think so.

Turn the screw on top of the regulator, no screw no adjustment.
Buy one, clean out the tbody, plenum, and runners while you've got diisassembled, and don't forget to put in a new gasket set, which should include throttle body gaskets.

 

Stock Fuel pressure regulators are non adjustable on TPI.
