Ok

got this.

12:1

Now.. from what i can see (by looking at this?) it seems this repaces the stock fuel pressure regulator? or am I wrong? Anyone got a diagram, pics on how to plug it in?

OOOOK

yeh the little barb is for the vaccume line..the bigger are in and outlet's ...and although it shouldn't matter which is which...1 is going tobe on the bottom of the valve and the other the top..meaning 1 way it could leak...the other it can't leak...

Now that little adapter...is the pinhole Through it?...and is the barb on it 3/8"? fuel line....if not then it's not for the fuel rail...

I have not seen one of those used on a turbo set up.
I would leave the stock FPR on there or replace it
with an adjustable one.
The FMU is supposed to work with the FPR and not ment to replace the FPR. With that Fuel adapter you would have no way of knowing what your fuel pressure is.

Hector- please man... stop now.

Why are you buying stuff you have NO CLUE WHAT IT IS OR HOW TO INSTALL IT OR WORK IT??

Are you just trying to add another think to your sig list?

The part I was refering to was that fuel adapter plate that you
were going to replace your stock FPR with. Don't use it.

Use the FMU. and keep your stock FPR. You can run this setup, its
just not very accurate as far as fuel goes.
An Adjustable (AFPR) would be better than stock.
You need both, an FMU and FPR/AFPR.
And of course the best method would be to get some kind of standalone
and ditch the FMU and keep the AFPR.

Hope that helps a little more.

If you look into the meets section of this site you can see my setup by looking at last years cars. I'm the teal MX-3. Not much has changed since then.
Thats in the Flyrtle Fladness meet.
Not to be confused with Goldmember, a different Andy. He has the gold MX-3 setup.
I have the millenia intake on my K8 with a bored out TB.
