Well finally got the tube inside the engine bay fixed. Not to hard once I saw how it all works. Tried to patch the tube but then it broke off where it goes through the fire wall. Tried and tried to repair that but it didn't work.
Finally went to the auto parts store and purchased a 3 foot line of 3/16 outer diameter vacuum line, drilled a new hole to the passenger side of where the old tube went in, (which is behind all the HVAC stuff in the center dash) and just plugged each end into the existing rubber boots on each end.
Its definately easier reaching the grey tube in the engine compartment from the top.
I'm wondering if the tube sealed itself when it melted and broke and thus if the switch worked for a while with the pressure that was left in the system.
