Vacuun pump failed?
Today noticed the vacuum gauge starting to inch upward. Climbed from 5.0
to almost 8.0 in 5 minutes. DG and AI acting normal the whole time. Then....dropped to zero and the gyros obviously quit. I only have experienced 1 vacuum pump failure before and it just dropped to zero without climbing first. Does this sound like the pump went?

Or a line or fitting fell off or started leaking.
Hope it's this simple, Peter

Yes it does. Another possibility is that the vacuum regulator valve has
gone south. Get a wet pump if you can. Rip RAM wrote: Today noticed the vacuum gauge starting to inch upward. Climbed from 5.0 to almost 8.0 in 5 minutes. DG and AI acting normal the whole time.

It sounds like your vacuum regulator quit. This made the pump work
harder which then died from over work. Make sure you check the filter on the vacuum regulator. The pump may have sucked in a chunk of the old filter sock on the regulator.

Make sure that your filters didn't get plugged up and collapse first. I've seen a couple of cases where the filters collapsed and essentialy the pump was sucking on a plugged line. Craig C.
