921.153101 will load up to 100 psi, (both gauges),only air hose will depressurization when placed on tire valve stem, but receiver tank stays at 100 psi. Is it a bad regulator? Thx

If the tank pressure is 100 PSI then the regulator will only go up to 100 PSI. It cannot increase pressure beyond the supply pressure.

That the line depressurizes suggests the regulator is impeding air flow.

Maybe dump the air, pull the regulator and put the coupler there, power up, and see what pressure comes out the hose.

Make sure you don't over pressurize your tire.
