I'm not sure that you need a pressure relief and a fuel gauge. Do cars have this? I know my Z car and most modern fuel injected autos require that you relieve fuel pressure prior to working on the fuel system. That implies to me that there is no fuel "overpressure" relief, but just that the fuel pump is designed to deliver just enough overpressure, and not too much. (I could be way off on this position).
My KR has 2 facets one per tank, with a gravity feed tank. I didn't want the overflow switch failing in flight and pumping fuel overboard. I have a three way fuel selector L-R and each side has a seperate fuel pump. The header has no pump, and no feed from the wings. It is simply gravity reserve. In effect, I have three seperate fuel feed systems that pass from individual filters to a fine filter, and gascolator before reaching the Ellison. The jury on the merits of this system will be out until after taxi testing.
