I just received my for regulator and fuel press gauge along with wiring , pump controller and return fuel line . Wondering best place to mount regulator , fenderwell or close to fuel rail ? Also wat port is in and wat is out of regulator ? I have no instructions . I think side is in and bottom is out but not sure . Also wiring kit only came with power wire to controller , wat size wire should I run to pumps ?? Also can run mine staged so only 1 pump runs full time but still debating if I should or not ? Any help is appreciated
