Thanks for the help! The tank is off and the pressure gauge that is
visible still reads 52. The switch is set for on at 40 and off at 60.
Should I inflate the new tank to 40? Should I change out the gauge?

Much appreciated help on a Sunday afternoon!

Replace the guage. Or clean out the hole into it, then take it apart and bend
components to adjust it as needed.
