How to setup an aftermarket FPR?

[cam_ra40]

I'm in the process of fitting an aftermarket fuel pressure regulator to my turbo 4agze. The factory FPR is after the injectors on the fuel rail and runs the return line. I've recently been told that I should set it up pre-fuel rail and block the return line. Any ideas or advise?

Thanks in advance

I set my Sard up after the fuel rail, as per stock. I figure that there's a reason it goes there....


Don't forget to set your pressure with the vac line disconnected and plugged.

Whoever told you that needs to be slapped. While many modern cars use a single-line fuel setup, your FPR is very likely not designed with that scenario in mind.
