    It is a return style with the vacuum regulator. But I have one with a torx and I adjusted fuel pressure to 60psi it stays at 60 all the time

    Whatever it was is internal motor died today. I'm guessing a small crack in a ring land expanding under higher pressures and it finally died after my many trial and error pulls
