It looks like this line , which is made of brittle thin plastic, runs from a passenger side port on the upper intake manifold to the gizmo at the end of the passenger side fuel rail (photos).
I snapped it.
I'd rather not have to buy a entire new harness (photo). I suspect its a vapor recovery line - from fuel rail, back into the intake.
I taped it up using and electrical butt connector and some electricians tape ...but on 2nd thought, not a good idea I think.

Anyone have an idea on how to repair?

Thanks
