EDIT: I'm thinkin' here - (see the smoke
) -
Is the regulator mechanically controlled? Or is it electrical, and it opens up and lets the pressure off when you kill the motor?
That still doesn't explain why you're supposed to bleed off pressure.................................

The pressure is controlled by an engineered compression spring and engine vacuum. The vacuum overcomes the tension of the spring via a diaphragm, hence the regulator leakage. You can test that by just pulling vacuum line from regulator to see if fuel is present.
