The tubing ends were flairs between a single and a double flair. I pulled out a insert that looked flat on the end.

I'm just about to ready to bend my fuel lines for a 1955 Imperial Sedan. When I noticed a flat copper flair not a double flair. Has anyone ran into this problem and do you use the double flair tube with another fitting???
