how hard is it to install an areomotive fuel pressure regulator on a 1990 5sfe?

About as hard as putting it on any other car. It's about buying the correct fittings.

The OEM 5SFE top feed rail isn't threaded. It's sort of a banjo style fitting. You can drill and tap it for M12x1.25 or buy Dr. Tweaks adapter.
