My original fuel line on the '65 Dart I bought in 1966 did not have a/c but had a fuel line similar to what you have pictured. I remember because I twisted the line accidentally trying to remove it and recall purchasing a replacement from the dealer's parts department. My current Dart Charger had a rubber line from the filter to the carb, but as I mentioned earlier, my car has been worked on carelessly over the years.
