I do not have any of the repair or maintenance books for our cars and cant find this info no matter where I look. Does anyone have any pictures of the stock fuel pressure regulator? How to adjust it? I checked the mirror site for MKIV.com and couldnt find it there either. Thanks in advance

It's non adjustable. You can see it, just look at the front of the fuel rail.

So buying an aftermarket one (thats adjustable) is beneficial?

i dont think you can use an aftermarket regulator on the stock rail, as far as i know at least.
