EFI stainless steel hardline project

[eamblk50]

I got the bug to take on ditching my braided ss lines for hardlines. Will be running a 5/8 feed and a 1/2 return. Bought imperial eastman benders and a Ridgid 37* flaring tool.

My q's are will. 035 wall seamless annealed ss tube work for both of my sizes? The 1/2 bender has a 1.5" radius and the 5/8 bender has a 2.25" radius.

Are there issues using aluminium tube nuts, sleeves and fittings with the ss ine?
