FPR is ALWAYS the last thing the fuel flow sees before it goes back into the gas tank.
All US-spec FC turbos should have the FPR on the secondary fuel rail.
Thus, fuel feed line should hit primary fuel rail first then secondary.
I've seen J-spec FC (they are all turbos) have the FPR's on the primary fuel rail, and their fuel system is basically backwards from the US-spec cars - secondary first and then primary.
If you indeed have FPR's on both primary and secondary fuel rails, you might have a mix and match of US-spec and J-spec fuel rails.
