Its on the fuel rail. There is an install guide in the DIY link at the top of this forum.
But what makes you think you need to install a 4 bar?
I am not even running 4 bar of FP and I have a BT!

Why are you installing one? Cause unless you are running 4 bar specific software or a bigger turbo than the stocker you will recieve no gains only poor performance from a 4bar FPR.

It's a hose, a clamp, and a C clip. Not rocket science. Look at it and you'll figure it out.

Do some logging.. Don't just "assume" that it needs more fuel!
My upsolute software runs almost a perfect A/F at idle and WOT with a gt28rs. So I am thinking that you are going to be running EXTREAMLY RICH!!!!

And don't foget to leave you key in the on position while removing and installing the FPR. Just joking. Please do not leave key in the ignition or it may squirt fuel out at you. And leave the driver's door shut too.
I don't have to tell you to not smoke while doing this do I?

I use an upsolute file and you really don't need a 4-bar no matter how much air you think its cramming down your engine's gullet. You'll just run rich.
