[70 tt rustang]

Hi all iam at the point where iam intalling my new fuel system. I wanted to get a second opinion on choosing the line for my EFI fuel system. Iam running pump gas. I was running standard braided line before with no problems but ive been told that over time like 3 years that the line due to the ethanol in the gas will make the line bleed vapor giving a gas smell and then become hard and have to be changed. On the other hand ive heard nothing bad about the teflon line besides the price. Does anybody have any fuel line opinions?
thanks
Rich
