I checked summit yesterday and they have right stuff 3/8" lines for $69(+an extra $10 for oversize). They don't offer a 3/8" return so I'd have to buy 2 feed lines but the return line is supposed to go over the crossover and travel along the front of the frame so I'd have to rework it anyway. Pretty sure I wouldn't be happy with it. All the while I'd be thinking I could make it for 1/10 of the money. I'm just hating on the aftermarket right now, don't mind me.
