Thanks again. Here's the plumbing progress so far. I'm still waiting on some fittings. I chose to use the poly line. It will make it easier to install. I hope..lol My question, what did you use to mount the new rail to the factory fuel rail? I can machine a chunk on aluminum I suppose, but if something was already available, of course that would make the most sense.

 

Actually...the stock rails have little tabs on them with holes drilled in them, I bent mine up a bit and drilled and tapped the bottom of the nitrous rails. You have to be very careful not to break into the fuel passage...but even if you do just use some thread sealer when you screw it together. You can see the tabs in your pic just sticking out under the polished rails. One of them is all the way on the left right between the first two fittings. They bend very easy.

BTW...looks friggen cool. Even the black plastic lines look decent now that its semetrical. No longer a "birds nest" lol.
