Default Pressure Regulator Failure

My car has a Holley Blue with a Holley fuel pressure regulator (12-803) as per the holley combo.

Went to tune the car and discovered a little gasoline fountain.

Swapped out the regulator for a new one and was still unable to stop the pressure overwhelming the carbie.

Put a fuel pressure gauge on the line to carby (after the regulator) and the 15psi gauge was pegged pretty quickly.

Is it possible that my fuel pump has suddenly got more pressure?

I notice that there appears to be a better/more heavy duty fuel pressure regulator 12-704 - anyone had any experience with this.

Open to suggestions
