Say Kevin, when I shut my oil valve then turn on the scavange pump, it typically takes 1.5 to may as much as 3 minutes (or so it seems--never actually timed it with my watch) until I hear the pump change tones.  I'd have to say that I don't think it was ever as short as 30 seconds.
 
Am I doing something wrong?
 
Thank you for your posts and all the helpful information.

Ted,
 
On the model 12, the only airplane on which I have operated the system, it typically takes about 30 seconds or so with oil that is high in the green arc.  The pump is just a bit below the bottom of the sump in elevation and the port in the oil tank is about 30 inches above the pump straight up.  If you have longer runs, it may be more work to get the oil moved.  If the oil temps are 160f or less, it will take a while as well.
 
Sincerely,

Kevin Kimball
