need help, return fuel line quesion for 5.3 swap

I have been searching this subject for a few hours and still havent found my answer, though I'm sure its here somewhere. I am working on getting my braided -6 lines run from the fuel cell to the fuel rail on my '99 genIII 5.3/4L80e swap into my '69 c-10 stepside. I used a russell fitting for an Lt1 (thanks 68 short step for the part # in a past thread) for the pressure side which works great, but my question is, what works/has to be done to hook up the return line to the fuel rail? Any help would be greatly appreciated!

The fuel side is a 3/8 barbed pipe, while the return side is a 5/16 barbed pipe. KLook for Russell part #640860

I was wondering if that was a different size for the newer lt4's. Thanks for the part # it just makes things go so much faster. Much appreciated!
