vacuum hose

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 this is a hard plastic line which is what it looks like, it is more than likely this is for the washer fluid. There are a couple connection points for this line so it may have just come off. If not, then it broke and needs to be replaced.

I am attaching the info for this line as it is going to connect to the nozzles under the hood and then the pump as well that is on the bottom of the reservoir.

Please see the attached info and let us know what you find with this.

Thanks

Turns out this is what it was. 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.

Thanks so much for updating us on what this was. That makes sense and will surely help others. Please let us know how it turns out.

Thanks
