I notice that a short piece of hose that appears to be some sort of drain for the ACC air intake tray above the blower is broken at the bend. If I have all of what broke off, it's a length of hose about 4" long, pinched at the far end and wrapped in wire loom. Is this a critical piece? Is there more than 4" to it?

Thanks,
Sixto
