I'm wanting to purchase an Andair fuel valve for my RV8, I can't quit make heads or tails which one I should be getting. My tanks have a return flow fitting. Should I use the FS20x7T or the FS20x20-3? Looks like the latter requires return lines. Is it better/safer/required to run the return line configuration?
To give some details: IO375 precision silver hawk fuel injection, efii boost pump and I'd like some way to purge fuel into the tank for hot starts if needed.
