A couple of months ago our AI, which had been "coming and going", finally
went. We replaced it with a rebuilt unit from "The Gyro House", which had
the dual effect of getting our autopilot working properly again.

Last month, our DG failed completely and suddenly, after a normal landing in
Pella, IA. Before that landing it worked, after that landing it didn't.
And the autopilot -- connected to the DG, too -- stopped working again.

So, I've just received a rebuilt unit from the Gyro House. As a precaution
(I'm assuming some sort of contamination caused the second failure), I've
ordered new vacuum hoses -- enough for my A&P to replace all the hoses, from
the vacuum pump to the firewall, and from the firewall to the two vacuum
instruments. I'm also having him replace all the filters.

Short of replacing the vacuum pump itself (which is still working fine), is
there anything else I should be watching?
