Alternatives to Braided stainless? Braided stainless is so expensive as we all know, as are the fittings. Are there any good alternatives that are cheaper and nhra legal? I know hard line, but is there anything that is flexible as well?
I also hear you get a bad gas smell through the braided stainless.

Pushlok stuff here too. I love the stuff!
I plannaed on running hardline through most of my build till I read that the hardline is a little smaller ID than the flexible lines. Not a huge deal by any means but it made me think and Im just using black aeroquip socketless.
One other thing though, I have heard people complain of gas smell with all braided lines.

If your going with -8AN(1/2") or smaller, you can hit up www.harrisspeedworks.com They are a sponsor that mostly deals with nitrous stuff, but they will put together custom length -3, -4, -6, and -8 lines. I'm pretty sure they are teflon lined, it says on the site they are rated for fuel, and the nitrous lines that they made for me appear to be teflon. You can also get the lines with a pvc coating on the outside, so they are smooth to the touch and won't tear apart anything they rub on.
Right now I'm running the stock 5/16" hardlines in my rx7 with regular -6 braided lines for connections at the engine. Haven't had any fueling problems yet, but I plan to get an aftermarket FPR and mount it in the back and just run a single -8 hardline under the car. I might use a few unions so the line can come apart at a few places, and make it easier to bend/run, but I don't plan on using many SS braided sections if I can avoid it.
Hard line with tube nuts and sleeves are pretty cheap, and a 37* flare tool isn't too expensive either. I was thinking about getting the $30 tool from summit...seeing as making single flares in aluminum tubing shouldn't take much.
If you do this anytime soon, feel free to snap some pics and post them here or on the v8rx7 fourms...I probably won't be doing mine until I address some other things on my car, and I'd be curious to see a similar setup before I go ahead with it.

I posted/deleted concerning teflon lines last night because I misread the post. True Teflon lines similar to brake & nitrous lines require crimp on connectors in the larger sizes. This can be a pain because you have to install & trim the hoses to fit, align the fittings, then remove & take the hose to have ends crimped on. Also most of these fittings are zinc plated steel because they are generally used for very high pressures. The nice looking anodized aluminum fittings are often not available for this application.
Teflon lined hoses on the other hand, as mentioned in an above post, do not necessarily have to be crimp type because they are essentially the braided rubber hose with an internal teflon liner.
