Turned off pump...released pressure through old gauge. Unscrewed the old gauge. Cleaned out the threads on Filter. Put plumbers tape on gauge threads and screwed into top of Filter. New gauge reading ~13 psi, which is right where it's suppose to be. Very easy/cheap fix and now I can correctly monitor my system pressure.
