Interestingly, I had readjusted the vacuum regulator about a year ago because suction was falling off. I had thought that suction had fallen off before the adjustment valve on the regulator had backed out a little. (The jam nut was a little loose). But when I did a test flight this morning, I saw my suction gauge showing 6". (Way up from the 4.5" I had had it set for before readjustment.) So, when you see your suction falling off and/or readjust your vacuum regulator, it's time to change your vacuum pump. Probably the same is true for your engine when you have to shim your oil pressure regulator to maintain oil pressure.
