There is no available adjustable pressure regulators on the market? I assume you may have looked but just curious.

Also I wonder if you could have issues with the pulse damper. It's inline on some cars and some it's built into the pump unit itself. Just as the name presumes it smooths out the flow of fuel from the pump since all rotary pumps don't actually deliver a steady flow under pressure. I have seen them become clogged with crap of years of use.

I can't remember exactly but can you or did you disconnect the vacuum supply to the regulator when you checked the pressure. Did it go up any? It should have jumped to about 65psi max. Atleast that's the highest I have ever seen one with a stock pump achieve.
