It is a double flare. it's a reproduction OEM material (plain steel) pump to carb line from "fine lines", purchased from OPGI. right after I got the carb back I had trouble with the leaks. since the carb folks test run the customer's carb on a Ford six, I was suspicious perhaps the carb side of the connection might have been damaged during there testing/tuning, and since the new line from OPGI leaked equally bad as the perfectly good stainless line I just removed. I'm putting a fire extinguisher in the car. Just because it seems fixed does not mean it cant crack unexpectedly
thank you all for your help and concern. MUCH appreciated.
