Upgrading the fuel tank

Thanks for all info guys! I have my fuel lines on order. I went with Russell an6 fittings and fuel line. Here's what I am thinking, tell me if i'm wrong. One of the fittings I purchased is a "T" which is were I am going to attach the return line, but I am thinking I should put right in front of inlet on the regulator. I'm hoping it will push enough through the regulator which is set at 5 psi. I also will be putting an inline filter in front of the "T" fitting.
