That's a first: fits in a Mooney but not in a 210! Ahh, but you're
turbocharged,
right, and the turbocharger is in the same area as the vacuum pump?

The turbo is closer to the exhaust but nonetheless it would be too tight a
fit. To be fair, the plane has two vacuum pump pads and used to have two
separate pumps; I took one vacuum pump off to make room for a standby
alternator, so I realize there is a limit to what can fit under the cowling
and the dual chamber vacuum pump was not that high on my wish-list because I
do have a vacuum AI/DG and an electric AI/DG. It turns out that my vacuum
pump failed so I was looking for options to replace it, and if the dual
chamber one had been available I would have considered it. There is enough
redundancy now that I would not replace the pump again without good reason.

That said, my plane before my P210 was a Mooney M20C... my mechanic says my
P210 is about the only plane worse than the Mooney from a maintenance access
perspective; maybe he is humoring me a bit.

I wasn't aware of that. Do you have any more information about that?

They sent out an email in very late 2002 advising customers that their STC
would be delayed by a couple months as they researched some potential falure
mode for the pump -- I cannot find that old email now but I will let you
know if I find it. You could probably ask AeroAdvantage for a few details.

I agree with you that there does not seem to be all that much to lose in
trying this out though.
