TPI fuel lines

What size is the fuel return line on a TPI thirdgen?
I'm planning a TPI swap into a G-body. I have ordered a set of Grand National fuel lines with the return line upgraded to 5/16" from the stock 1/4". If this wasn't necessary, it's not too late to change the order back to the stock line.

Thanks...

Been there, done that.

The supply line is 3/8", the return is 5/16"

Thanks,
I was starting to sweat when the tubing vendor called back to double-check my order. The custom piece adds a week to the delivery date. The waiting begins...
