    Ain't these the drain tubes?

    If they are, I haven’t seen them. Are they under the seat?

    You probably have to remove the sheet metal plate under the cab for access. Serial number required for more info.

    SIS is a bit ambiguous on this one. Valve #4 is called a check valve and I'll bet it has something to do with the drain system. Hope this helps.
