Jim the thread/string was behind the flare on the line between the flare and the nut that cups over the flare. If it's use was a gasket I would think it would be between the female flare and male flare, if that makes sense? I thought it would cause the nut to be tighter at the back of the flare.
I have my sediment bowl and line out of the car and hand lapped them together for a period of time trying to knock down any high spots. I believe I will do one of these copper washers just to be safe. I can't see it hurting anything. I'll bring this back up after I try it.
My line is steel and the sediment bowl/flare is cast pot metal? I don't think the copper washer would cause any problems, would it?
