I am trying to "install" my engine dehydrator. I am using the "BlackMax" from Aircraft Components Inc. in Findlay OH and the owner is trying very hard to be helpful. I had the dryer beads model on my 7A but I am running into issues putting the same idea into practice on my new-to-me 12. The model of the dryer is not a factor because they both work the same way on the engine.

The dryer pumps dehydrated air into the oil vent and thus into the rest of the engine. It worked fantastically well on the Lyco-clone but this is a Rotax. There are 2 tubes coming out the bottom of the engine compartment.
One tube is clear, flexible plastic or vinyl and the other is black rubber. the clear one has an ID slightly larger than the rubber one. The rubber one has, of course, larger OD. Both are much smaller than the vent on a conventional 360" engine.
Q1: which tube is the oil sump vent and what is the other one? I found the source at the top of the oil tank just below the filler cap but there is so much stuff in the engine compartment that it's not obvious what I want to know.
Q2: where is the hole in the oil vent tube that is often called the "ice hole"? the pressure from the dryer pump has to be upstream of that.
THANKS
