Dripping Pipe Forward of Firewall

[BarryBD]

Hi everyone. I'm totally new to the forum. Hi!

I've just starting parking my 2005 Escape in a garage (previously on gravel drive) and am noticing a small puddle of what appears (and smells) to be plain water. I've traced its point of origin. It's coming from an open-ended pipe that comes forward from the firewall .. low, near the bottom of the firewall. I've included 3 images here to describe it better.

The first one is from the ownership manual, showing the general location of the pipe ...


The second one is a general shot of the main engine components. The pipe is dark and out of focus ...


The third one shows the pipe itself properly focused and exposed ...


I'm suspecting it may be an airconditioner condensation draining pipe .. but I can't find mention of it anywhere. Does anyone have knowledge of this pipe?

Thanks in advance.
