feed and return...

so a rule of thumb could be, feed to where the pulsation dampner is. wich has the vacuum line coming from it...

wich in my case, its turbo. so feeding to the secondary is the way to go...

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.
