Some times the little filter under the regulator can get cloged up and give you hi [PSI] Or you might have a small kink in the return fuel line from the pump area, Or a blocked fuel line fitting some place, I have seen where a fitting was not driled out enough Or at all and that could show hi fuel pressure some times. Or the regulator is getting ready to go out.

I'd double check the gauge with a test unit. Likely that the regulator is clogged up with some crap.
