Just a further note - i wouldn't try to get plain stainless lines and try to put the fittings on the ends, there are no simple flaring tools available that can handle stainless tubing well at all, much less form a doubled flare. That's why look for straight lengths of line (Stainless fuel lines work well, they're the same) that have the fittings and flares at each end. They should be available in many lengths...
