I have a few questions about the fuel pressure regulator for a 2001 AWM

What is the rising rate? 1:1?
What is the static fuel pressure? 43.5 psi/3 bar?
Does it have a return line?
I have an Aeromotive 1:1 fuel pressure regulator which I used on a custom turbo setup a few years ago and I was wondering if it's compatible with the fuel system on the 1.8t, assuming I deal with the fuel lines. If I ever upgrade the fuel system I would rather use that instead of buying something to save money. Otherwise, I'm just going to sell it.
It looks like this.

it is 3 bar at 0 psi. It is ~1:1 rising rate because of the vacuum line.
no real reason to mess with the FPR unless there is tuning requiring it.

unless I acquire a setup that requires some different static fuel pressure, which I would be hesitant to use... all fuel injectors are rated at 43.5 psi / 3 bar which is the fuel pressure they were designed to operate at. I have seen some setups where the static fuel pressure is increased in order to compensate for injectors which are too small, but that opens up a can of worms like an injector duty cycle which is way too low at idle, absurdly high fuel pressures under boost pressure, etc... I would like to avoid that.
