Can you provide a description of where it comes from and where it is located on the car?

I have the exact same hose broken on my 2000 Taurus. This is on the passenger side and looks like it runs through the firewall. It appears to have something to do with the heater, but I am not sure as I had several other lines that needed replaced as well.

If its there then it feeds to a vacuum source and reservoir. It uses the line to supply vaccum to theclimate control head to control theblend and mode doors

Turns out this is the vaccum line for the windsheild washer sprayers. From where it is shown in the picture it needs to run under the insulation on the bottom of the hood. The connection is hidden under insulation, so it will need pulled back.
