I have aluminum fuel line on my Dart. I have lots of mounting clamps (rubber insulated). Also where I connected my AN fittings I used the AN compression fittings that have a rubber bushing for sealing. I didn't flare any ends. Although I never gave any thought to flaring making a stress area prone to cracking, but it makes sense. I just wonder how long the rubber liner of the braided lines holds up to the gas??? How long do you run yours until you replace it?
There is no visible damage in my 20 year old lines. I sold most of the old stuff on ebay to offset the cost of the new stuff.
