This month's issue has an informative, and for me timely, review of Vac
Pump options. It's time to proactively replace my Parker Hannifanb
model at annual in Dec (1,000 hours). They review 3 possible
replacements Tempest, Rapco and Aero Advantage (dual chamber). The
former 2 have wear view ports.

They didn't cover the new wet pump which had caught my eye.

The Tempest may be my choice. Any opinions?

I haven't seen the article. Thanks for the heads up. We just installed the Aero
Advantage STC at our last annual. Seems fine so far. Installation was smooth
even in the tightly cowled Mooney.

See http://www.employees.org/~dgbutler/201/201.html for some comments and links.
Look for "Vacuum redundancy".
