Teflon tape is helpful on the threads of bleeders.You can vacumme bleed w/o pulling air down the threads.

Re: Teflon tape on flare fittings
 

The only time I've seen teflon tape or thread sealer used on flare fittings is when someone uses stainless steel lines. As most of you know, they can be a bear to initially seat and seal without drips. I think many folks do it out of frustration. The slick setup for stainless fuel lines is a copper insert that goes inside the flare. A mechanic who retired from a Caddy dealer after many years had a bunch in his tool box. I don't know if you can still get them anywhere but they sure made sealing up a 427/435 vette with stainless fuel lines pretty easy. https://www.yenko.net/ubbthreads/imag...mlins/flag.gif

Maybe if they made the fuel lines sets in the U.S instead of China,Hong Kong or Mexico they would seal better ?

I had a problem getting the lines to seal on the 69 Z... I had to seat all the fittings separately anf then install the whole setup... they leaked like a seive before...

Without a doubt they would be better. You wouldn't believe what I am going through buying ONLY American made parts for the Nomad Gasser project. The only thing I HAD to buy imported were the ET 10 spoke wheels, and it killed me to do that.

Re: Teflon tape on flare fittings
 

The inside taper on the tubes seems to be the problem... they are misformed or not fully formed.
The only way I could get them to seat was to take them one at a time and snug it down... then rotate the line 360 deg a few times and it would get looser... snug again... and repeat a few times... then I tightened them up on the car... viola no leaks! (you may be able to use a dbl flare tool and reform the inside tapers)

As some of you know the reason that the stainless wont seat properly is that its too hard. They should heat treat the metal tube so that it softens it to the sam RC as the steel ones.It would then seat great and look great.
DA-----HHH.
