Yes, the engine windmills very nicely.  I usually just let my 2nd fuel tank run dry, when the power drops (out of gas) I just switch tanks and it starts running in less than 2 sec.

The fuel pressure goes from about 42 with the engine off (29.9 MAP) to 32 at idle (14" MAP)

In fact, I just realized why I run so rough on desent.  The MAP is probably getting pulled down below 10" and the pressure probably drops even more making it very lean...  hmmm  :-)

Two questions: Does the engine 'windmill' if turned off during cruise?

                        How much does your pressure regulator drop the
pressure at low MAP?
