Replacing copper fuel oil line


I have a leak at the pump fitting and need to replace about 3 feet of copper line between the filter and the pump on my oil furnace. The OD of the line is 1/2". Questions:

Is the flair a single or double flair?

Given the OD is 1/2", what ID would I expect to find when I remove the line?

I've read there are newer coated copper oil lines used today but this installation is 42 years old so would they have just used flexible copper line? Can I use the same thing?

It is a single 45[SUP]o[/SUP] flare. The I.D. of the tubing is irrelevant as copper tubing is sized by its outside diameter. As long as the tubing is above ground you can use regular copper tubing.
