I know this will be a n00b question, but why do you need new fuel rails when putting an RE motor into an FD?
because the lower intake manifold is different than the FC/FD...and so are the secondary injector locations.

The injectors I'm wanting to run are not drop-ins and I also would like a little more volume than -6AN....it's going in an FC not FD :0
The injectors I'm running are "stock" if that's what your asking. I will be running 850cc/1680cc on my RE manifold...once I get everything in place.



What HP are you shooting for? I have dual pumps each feeding one rail and then both "Y" into an aeromotive FPR, so I have one -6 line to the primary and one -6 line to the secondary.

thats just it... everyone thinks they need -8 or larger! Anything larger than a -6 is a waste of space. You can't get any better than what jspecracer7 has. Thats something I'd like to do this winter, mod my rails like his.



jspecracer7- do you have any kind of pulsation dampener in your fuel system?

I'm thinking that maybe -6AN will do ok, since you guys think so. https://www.nopistons.com/forums/pub..._DIR#>/dry.png I have some "bulk" aluminum fuel rails that are already tapped for 1/2" NPT, so I'm not sure yet.

I think if you were to run -8 from the fuel tank to the primary rail, then the secondary rail, then the regulator and back to the tank that it would work fine. But since I'm running two -6 lines from the tank...can't be all bad https://www.nopistons.com/forums/pub...DIR#>/wink.png



The aeromotive FPR also acts as a fuel pulsation dampener.

That's all my rail is! Get to work and make your rail! https://www.nopistons.com/forums/pub...1047683329.gif

looks like I need to get my hands on a aeromotive FPR and a few -6 male jic plugs from work then! https://www.nopistons.com/forums/pub...IR#>/smile.png
