I was replacing the main wiring harness in my '91 GT (electrical fire at coil/solenoid, ughhh) and yanked on "something" to get some slack in the bundle which resulted in a slight "pop" sound followed by the pictured hose coming out. I can't for the life of me figure out where it goes. It originates from a brass 'T' on the underside of the upper intake manifold. The other side of the 'T' recirculates into a port underneath the upper. The end of the hose has a circular metal connector with a one way valve hole (?) in the middle.

Where the heck does this connect to??

My guess by the looks of it is the pcv valve at the back of the lower intake, it comes out fairly easy. And that diameter hose looks about right for it.

PCV valve. The hose in the first picture connects to the underside of the front of the manifold. Goes to that T fitting, then around to the PCV valve.

yep looks like the pcv. should be a grommet in the back of the lower intake that you pulled it out of.

Hi guys. Well, the reason I was so freaking baffled about fitment is because the PCV grommet has either disappeared or was never there in the first place! Looks like I need to find a grommet at the local parts store. Thanks again.

I'd recommend using a Motorcraft grommet and PCV valve (they fit together tight - some aftermarket stuff does not).

You can also get a grommet (from Motormite IIRC) at the parts store.

Make sure the 'breather' is in place in the lower intake. It goes below the grommet and valve.
