Evap line

I plead ignorance here...I should know, but don't. On my '97 3.1, there is a plastic line that comes over the top of the master cylinder and has a service port with a green cap and a tag that says something like "Evap check 1 psi max...blah blah..."

This line goes to SOMETHING on the firewall side of the motor...but after doing the lower intake I found it is disconnected, and looks like it is missing perhaps a rubber end that allows it to plug onto a valve.

Working by feel, I can't find where it belongs. I need to get a mirror back there or roll the motor forward and look, but if someone knows where it goes that would help. And if indeed it is missing a rubber end (maybe it's still stuck on wherever it goes?)

I hate when I miss a minor thing on a major job. I should know what's back there, but was so focused on the intake job I didn't pay any attention to what else was there....

That line goes to the purge solenoid valve......should have an emissions label showing it.....

Cool...I see it now, thanks! Up under the coil packs....
