I have a fuel injection system that requires a return line. My problem is having to put two fuel pumps in the tank, plumb -6AN min line up to the cheesy plastic tank selector valve (which is smaller, hose clamp fittings and not pressure rated) and then how to select which tank the return line goes to. What I'm looking for is a nice 6 port block with -6AN fittings and electric selector valves. Anyone have any info, suggestions or a better way to do it? I have considered a surge tank like Edelbrock or FiTech but am still stuck with the return line issue and the selector valve.

Thanks
