Was flying along and noticed my AI was sitting cocked looked at vac and
had none. Anything I could look at other than vac pump on the fritz?
Last time I lost vac it ws in a cherokee in 1968. That time the vac
instruments moved around, very confusing. This time nothing is moving at
all. Anyone can say how to test pummp easily? (hate the thought of
haveing to remove as that bottom nut is a bitch to get to) Charlie H

FOR SALE.
I thought that I could use a FAST STACK PRO-G HUB when I wired up my
airplane but didn't use it. I would like to sell it, new in the box,
harnesses available for most radios and other popular applications or you
can wire your own. Prices are on their web site.
http://www.approachfaststack.com/products.html
as you can see from the web site the price is $489 and I would let it go for
$300. i will guarantee this to work, again , it is new in the box.

You didn't say how many hrs on the pump. I don't believe in more than
300 to 500 then replace. They can fail anytime tho.
I'd check hoses first. If they are secure you need a new pump. It
isn't likely your regulator turned itself off.

When my AI failed a few years ago it did exactly what you describe (in the
clouds of course). My DG was still working, and my suction gage still showed
in the green, so I knew it was the AI.

It is worth borrowing or buying the Rapco wrench for vacuum pumps. Makes
the bottom nut not too difficult. It is not unusual for vacuum pumps to
get just enough engine oil, either from the garlock seal failing or just
from other leaks to introduce enough drag to cause the drive coupler to
shear. I don't recall whether it was Tempest brand or other than now
makes the drive coupler area protected from oil.
