Realized I never answered you.  It's 12" - the tape is my mark for stopping when I shove it up the breather and it was marked visually with the cowls off to make sure the stopper goes past the hole.

 

 

 

I have the same situation with the breather hole in my J.  The Engine Saver manufacturer will provide (for $14) longer tube that allows the foam seal to be pushed past the breather hole.  One thing I've noticed with the design is that the foam seal is not very durable and starts breaking up after several insert/remove cycles, so I am looking for an alternative and would appreciate from any of you that have dealt with the issue. 

Overall, the Engine Saver works well with my installation in the engine breather tube.  Using a temperature/humidity data logger that I place in the exhaust pipe, I see the humidity drop from 76% measured about an hour after a flight to 17% within 10 hours, and eventually to a low of 10% after ~2 days.  These results are using recently dehydrated silica (3 hrs in the oven at 300 F) and will diminish in effectiveness over time as the silica absorb moisture and its time to dehydrate again.

With the black max dehydrator, you just loosen the oil filler cap and it pushes dry air  into it. No return no beads nothing like that
