Anyone used this stuff? I know it advertises weight savings, which I don't care about really, but It seems like it wouldn't fray and you wouldn't have to worry about it rubbing against something.

 

yup I used that on my friends GTR when making his fuel lines. It seems like quality stuff, but if you thought it was a bitch to get steel braided into the fittings... have fun with this. You basically have one shot at it until it frays and you need to re-cut.

the black is a nice touch, keeps it low key and MUCH les abraisive than steel (on painted surfaces and charge piping etc.)

 

That style is all my roommate runs on his eclipse, and is what I am going to use on my fuel lines as well. It bends easier/ looks more low profile/ basically kicks ***. We both are using the Earls brand though. I think it's called pro-lite 350. Available at Summit, amongst other places...

 

I imagine assembling 4AN nylon hose is an utter nightmare then.
