Pretty sure it would have a 4 bar like the B5.

Default B6 has no FPR
thats why it's a return less system there is no fuel pressure regulator to limit how much gas goes back to the tank.

I thought there was a FPR of sorts built into the filter on the B6?

Default I've seen diagrams of it. It has a fuel pressure regulator built in. it just isn't a rising rate FPR
like the B5's use.

Default did a little research
B6 models use 8E0 906 087P fuel pump and 441 201 511C

The B5 uses 8D0 906 089A fuel pump and 441 201 511C non DBW and DBW cars...

the B5 and B6 use different relay but other than that nothing in the lines that i can find on the ETKA...

but this is my findings on the ETKA and EIS CD. if there is a regulater that would be news to me

Default B6 1.8T fuel pressure regulation is done at the fuel filter.
Don't ask me to explain it, I'm not even sure I understand it....

Default Here's a cut & paste, right out of AESIS.....
The fuel pressure regulator is located in the fuel filter underneath the tank.

Fuel pressure regulator regulates fuel pressure according to intake manifold pressure. This ensures that the pressure drop at the fuel injectors remains the same for each speed and load range of the engine.
