Fuel line BB vs SB

I'm looking to replace my 5/16" tank to pump fuel line to a 3/8" fuel line. Looking at the Summit website and talking to the Summit salesperson, I see that BB and SB are (what looks like in the product pic) completely different. Originally my car left the factory with a SB but has since been changed. Which is the correct fuel line at this point?
Part numbers at Summit are:
FGL6703 for SB
FGL6704 for BB
Thanks in advance, Jim

6703 is the supply line from tank to pump.
6704 is the return line from filter to tank.
But, I believe '67 came with two line diameters, 5/16 for L6, & 3/8 for V8's, but no return line.

For stainless steel https://www.summitracing.com/parts/r...923s/overview/ Foe two piece regular steel https://www.summitracing.com/parts/r...6901/overview/. Here is a 25' roll of 1/2" aluminum fuel line. It is what I used on my 67 Camaro. It is easier to use than any of the steel lines.
