The substrate-tuned boson localization and the phase boundary properties of the adsorbed superfluid 4He films were analyzed. The torsional oscillator technique was used to study the superfluid response of the 4He films. The phase boundary in the temperature-coverage plane had a universal shape. It was found that the inert coverage did not scale with the Van der Waals constant, but showed monotonic dependence on the well depth of the 4He-substrate potential and the 4He substrate binding energy.
