Are the fuel line flares for the gas tank and inline compression fittings 37 or 45 degrees? Would a copper nickel or aluminum line require a single or double flare? It appears the old steel lines are single flare. Thanks.

I hope that you are using flare fittings and not compression fittings. You should be able to measure right off the fittings. The union would probably be easiest to get out where you can see it. I would be surprised to see single flare but it could very well have had the lines replaced by a PO.

Poor wording but I see the diff now, thanks. The lines are hacked and original so it's difficult to tell. I understand that steel lines are normally double flare 37 degrees.
