Steel braided line for return?

I am working on getting my new gas tank installed on my 70 swinger and had a question about the new return line. Car currently is running an Eddy 650 Thunder AVS and performer fuel pump.

It never had a vapor line before, but the new tank has a 1/4" provision for it. My question is can I run a 1/4" steel braided line along the frame rail following the existing 5/16" fuel line up to the Wix filter that has the return provision?

Thanks!
