not sure about it though, worries it may not seal after flaring

i had this bookmarked for the day i need more than the 3/8" line can deliver: http://inlinetube.com/Straight%20Length/straight.htm
i figured i'd ship them my OEM line so they could send me back a pre-bent 1/2" line with -8AN fittings. less problem & work for me

well i did a little more looking and i can find some air-craft seamless tubing at 0.035 thickness which i believe, correct me if im wrong, i you dont have to double flare the connections and can use a single flare.

The thick wall stuff is a bastard to flare. I took some line to several shops and even the "good" flare tools wouldn't do it.
I go through the brewing companies and use the thin wall 1/2" tubing. I single flare it. My fuel system has seen over 80psi. .020-.028 wall thickness. I've used it on several cars now. I flare them with a craftsman kit. I use B-nuts and collars. I'd have to double check but I believe I used .020 last time.

Have you been able to get good bends without it kinking?

I've done sweeping 90's with a 5-6" radius or so. I usually run it the length of the framerails and follow the fire wall half way up. Then I go with braided stainless from there. It will kink if your not careful, but I've yet to damage a piece beyond using it. I've done it on 3 cars now without issue. I heat it with map gas prior to flaring helps too.

This is the tubing i ended up with

Ill be installing next week. I have a good flare tool and bender so it shouldnt be too much of a problem. My plan is to run braided from the tank to the hardline mounted inplace of the current factory set up, and switch back to braided again in the engine bay. Will try to post pics up later

this is what i found, if someone has something different let me know
Lines: All non-OEM fuel lines (including gauge and/or data
recorder lines) must be metallic, steel braided, or NHRA-accepted
“woven or woven-pushlock.” A maximum of 12 inches total (front to
rear) of non-metallic or non-steel braided hose is permitted for
connection purposes only; individual injector nozzle and motorcycle
fuel lines are excluded. Fuel lines (except steel braided lines) in the
flywheel/bellhousing area must be enclosed in a 16-inch length of
steel tubing, 1/8-inch-minimum wall thickness, securely mounted as
a protection against fuel-line rupture. Fuel lines may not be routed
in the driveshaft tunnel. It is mandatory that fuel lines passing
supercharger drive belts be steel braided, NHRA-accepted woven
or woven-pushlock, or be enclosed in protective steel tubing. A
current list of NHRA-accepted woven or woven-pushlock fuel lines
is available on NHRA.com. All NHRA-accepted fuel lines must use
ends that are specifically designed for the type of fuel line being
used. No hose clamps allowed on NHRA-accepted fuel lines.

I do find it odd that it mentions no lines in the tunnel. Thats where they are from the factory. wonder if they just have to be a certain distance from the drive shaft
