I'm looking for the simplest and most correct solution, and I seem to have it with the Edelmann nut and ferrule on the hard line from the tank to the flex line going to the pump.
Thank you everyone for setting me straight. And as Charlie said, my hard line from the pump to the carb already has Edelmann nuts and ferrules on both ends. I took it apart to check. I've looked at it in the past, but I guess it got recorded incorrectly in my memory.
