I'm trying to run the stock fuel tank. Also, debating if I need a return line. It's an eddy carb, so I believe I need just 5psi.

The return line isn't about the pressure. It's about keeping cool fuel at the carburetor and relieving some stress on the fuel pump. With ethanol swill, it also helps greatly with drive-ability.
