Aftermarket Fuel Pressure Regulator....
OK, since i lost all my info about doing this i need your guys' help....
i bought an Aeromotive FPR and it comes with no fittings, the one's needed to fit onto the FPR are -6 AN fittings, now, what size is the existing fuel line?, i was told 5/16 but was i mistaken?...
needless to say, any help and guidance installing this will be GREATLY appreciated!...

Yes, the FPR fittings are -6 AN, but they are SPECIAL ones.
Check the hole, and it should be chamfered?
If so, you need -6 AN *flare* *o-ring* fittings to go into the FPR itself.
Yes, the stock lines are 5/16".
Adding such an aftermarket FPR is not easy.
It gets expensive due to all the AN fittings and especially if you go with AN SS hose.

the fittings i need off the FPR are -6 AN, but since i'm getting an M12 x1.5 barb fitting for the end of the fuel rail, couldnt i get the -6 AN fittings and another fitting for the end of that to adapt to the 5/16 fuel line?...
from the rail to the FPR, the other line goes BACK to the rail, or where does that one go?...

There's a machined bevel on the edge?
Don't you have a Kouki FC?
The problem is that -6 AN = 6/16th's or 3/8th's.
-6 AN hose is slightly larger than the stock 5/16" pipe size.
It sounds like you're trying to run it like the stock system.
The return line (bottom of the FPR) goes to the return pipe back the fuel tank.
The other port of the FPR is just blocked off, since you're not using it.

-5 AN is an odd side, so it's really hard to find that hose...nevermind the fittings.
Doulble-clamp the -6 AN hose onto the existing 5/16" pipe should be okay.
Good luck!

I know this thread has been dead for a while but...
Is there such a thing as a 5/16 to -6 adapter?
Like on a S4 rail, just remove the stock FPR, and run a -6 line to the FPR. Then have the return line clamp on the the stock rubber fuel hose?
Or if such an adapter does not exist.
Rail-barbed fitting-clamped -6 hose-FPR-barbed fitting-clamped stock hose?
Could that work?

Here you go.

You'd need an adapter if you wanted to go to 5/16th.
I don't know size conversion but you may be able to get away with

Sorry to steal the thread but does anyone have any info on the ebay special FPR's? I asked the seller if it referenced the boost with a 1:1 ratio and s/he said it did. Should I bother to try it out (its only $25) or should I go Aeromotive?
