I don't know how much about them. I understand what they do, but I don't know anything about brands and such. I'll be replacing my fuel rail, so I believe I'll need a new one.

Can anyone give me some advice?

 

The aftermarket fuel rails I've seen have provisions for the factory FPR. However, in my opinion there's no point in upgrading the fuel rail without replacing the FPR. In fact, I'm thinking the FPR should be done first, you can probably get away with the OEM fuel rail. I've seen FPS that bolt right up to the OEM fuel rail and I've seen external FPRs that use an -6AN adapter that bolts to the rail.
