Indeed, RON was the star in all of this!
I received the regulator about a week after he shipped it, but I only got around to doing it today, as the dealership took their sweet time to supply me with the housing connector which plugs into the regulator itself (which was broken as well).
Anyhow, for those who might be interested; the job is an easy one of course, you just have to unscrew the old regulator and screw in the new one using an adjustable wrench. I did nothing else and the car just worked as it should and performed perfectly while taking it out for a ride.
That being said, if anyone finds themselves in the same position; you can indeed swap your broken regulator with a different one, if you're capable of locating one, thus saving yourself a few hundred bucks that you'd spend on a new pump.
Again, thank you RON for going out of your way and shipping the regulator, you're a star
