Pressure Regulator adjustment?

Phil Payne mentioned the adjustment screw, but I haven't found one either.  I think he may have meant the pressure accumulator, which is located under the car - that I believe has an adjustment screw.


[Thus fuel distributor and both lines that flow into the pressure regulator
are flowing but nothing is coming out of pressure regulator.  Thus either
the pressure regulator is clogged or bad, or the fuel pump isn't pumping
sufficient pressure or both.

I've filled the pressure regulator with carb cleaner and have it sitting in
a sealed glass container.  I'll leave it soaking overnight and reattach
tomorrow.  Someone mentioned that they had an adjustment screw.  This one
does not.  And its the only part that I've seen that doesn't have "Bosch"
(or any other brand) stamped on it.  One end attaches to a plastic hose that
leads to a large container near the right fender.  I assume that fills with
air in order to keep pressure when the car is shut off?  I'm assuming
there's no benefit to filling that end of the regulator with carb cleaner.
