Racetronix was talking about putting something like this kit together to accompany their 8an feed / 6an return stainless sending unit. Last i heard they were talking february availability. Maybe they'll chime in here. I'm anxious to do this also whether i need it or not. Once done, it'll never need to be touched again as long as the transition from 8an to the rail and from the regulator to the 6an return is done correctly.
