Yes that's the post I was referring to from jeffturbo. The vlave he used is from DMGRS sold normally as a plenum valve and modified. Extensive description on "how to" in the thread, but Ben has no access to it yet! If its not just a misplaced hose, best to contact Austin Garages and/or DMGRS right away.
Any way to 'fast-track' full membership for him Tim, Nich ?
