The fitting on the bottle that the hose has been fastened too, has that been changed to one with an I/D of 1" or so?
Don't misunderstand me. I like the idea of the air/oil seperator, and have done enough work on piston powered planes to understand how they work, so I did follow the supplied link. I saw the fitting the web site displayed on the input side, and quickly discounted that as being too small for a crankcase breather. The aircraft background teaches the potential for ice buildup in areas like this. Maybe it was for that reason it didn't occur to me (at the time) that the tank could be modified, or maybe special ordered with a different type/larger fitting? Judged the potential of the tank too quickly I guess... My apologies.
