OK CADETS PT-17 Stearman
Had two hoses from rear cockpit to the front cockpit
One was instructor to student communication tube
One was a relief tube.
If you had to use the relief tube make sure you did not use

Was the funnel on instructor or student end of communication tube ??
Did instructor sit in the front or rear cockpit ??
