Fuel Line Question

[slyck68]

Well it may sound stupid, but this is my first build and I want to be sure I'm doing it right. I'm learning as I go. I'm building a '68 Firebird with a carb sbc with an Edelbrock mechanical fuel pump with 3/8" inlet/outlet. Year One and Classic Industries sell 3/8" fuel feed line but only 1/4" return hard lines. I like the idea of using a stainless steel braided line anyway, but wanted to be sure I'm not doing anything wrong by running -6 AN (corresponds with 3/8" right?) line on both the inlet and outlet lines. What is everyone else running for carb engines? Thanks guys.
