Pete, I cried for about an hour but now I'm all better
To answer arthurrs question, I have to admit I still used s/s braided line during my Cobras fuel system installation but it was the teflon inner and only 8" from the sump to the fuel pump and again two 6" from the regulator to the carb inlets, the rest is 1/2" alum. tubing. I originally used 1/2" rubber fuel line where the sections of brailed lines are but NHRA gave me a hard time about it, so I reluctantly replaced them with the upgraded lines. That was two years ago and no problems...yet. The only problem is we know rubber lines deteriorate but we can visually inspect their condition unlike the s/s lines. After all this talk I'm probably going to go ahead and replace the 2yr old sections and dissect the old sections although I know some people with 3+ yrs on their upgraded s/s lines. (cheap ins. you know) I'll give a report on my findings...if anyone is interested
