I do not have that unit anymore. So I can't look at it. If I remember correctly someone bought the Threaded-Trapezoid version for Prism not long ago. Maybe they are here and can give a feedback.
I still have some bits and pieces of it with hoses so I might be able to check it for you.
All you really need is a hose with a cuff diameter ~40mm.
Then you just clamp your existing hose to our BOV nut assembly.
Note: I would never use zip-ties to attach hoses. Zip-ties have tendency to self-tighten and can cut through the hose, also they can break off suddenly. We use SS hose clamps with layer otr two of electrical tape beneath to protect the hose.
Thanks very much for the info Jakub. And I agree about the ss hose clamps, that's the way to go if you don't have an Inspo. But another question: Do you believe there is any significant hydrostatic/performance difference btw a 2nd stage mounted as yours is on the bottom of the unit as compared to one mounted on the front of the BOV like the KISS unit?
