EFI fuel line, single or double flare?

I'm planning on using a Walbro pump and vette fuel regulator at that gas tank.
From there I was going to link up using the existing 3/8" hard line to the front of the car.
BTW, I'm aware of the differences between JIC/AN/SAE/45/37, etc fittings.
My question is at under 100psi, does the steel hard line need a single or double flare?

I always double flare my lines and it's mandatory for brakes, but lower pressure fuel lines may not be a problem. If you have the flaring hardware I would double flare it.

Double flaring will give yoy a much sturdier connection. You have more of a chance of a single flare going bad and breaking, then a double flare.
