Interesting progress here.
There seem to be 3 parts to the AOS upgrade issue?
1. substitute barbed brass pipe connectors into the stock plastic connections of the AOS - cut +epoxy.This allows easy connection of generic hose.
2. collect any oil condensate from a correctly functioning AOS in a small catch can -like the Jegs one linked previously.
This also serves as a catch for any larger volume of oil dumped when the AOS diaphragm begins to fail . Functions as a visual early warning system ?
3.The big challenge is to upgrade the material of the diaphragm to something that is unaffected by heat & oil fumes. Viton seems the obvious choice but I am guessing. Replacing the diaphragm would require careful slicing of an old AOS and then glue-ing in a Viton replacement. A 9" diam plain Viton diaphragm is $7 on EBay.I have no idea if it would work but is sure big enough for several attempts !!
