I am curious of opinions out there. I currently have a wet Vacuum pump on my
Glasair I-RG. I am considering adding an M-20 vacuum pump oil seperator just
for the vacuum pump since I also have a Christen inverted oil system
seperator
which takes care of the Crankcase breather. I am also considering changing to
a
dry vacuum pump. I am tired of loosing a quart every 4-5 hours and oil mess
on
the belly. What should I do? I do plan to use the plane for some hard IFR, I
will be working on getting my instrument rating this winter. Will the M-20
catch 90% or what percentage. Anyone out there using this M-20 model 600WP
unit
for vacuum? at $360.00 I don't want to be dissapointed.

Wetter is better!

The wet pump on my Bonanza outlasted 3 engines and, ultimately, the
airframe.


Hard IFR in an aerobatic aircraft, hmmm....

Better to ditch the vacuum system altogether and put electric gyros in
that can be easily switched off when not needed.
