So I am wondering about fuel return lines. I do not even have a clue has to the type of engine that I am going to put in my 7 but I wanted the option if I needed it. So I put a return line on my right tank. I am in the process of building my left tank and wondering if I can just run a dedicated fuel return line to the right tank and not have one on the left? I understand that I would need to be aware of running fuel out of the right wing first to avoid running fuel from the left and overfilling the right. Is this a good option or could it lead to problems that I am not even thinking of? If I do end up putting a return line in both tanks how hard is it to plumb the fuel selector? Thanks for the info.
