Hey 'Teg guys...whats this?
 

I cant find this on any parts diagram...

weird i don't recall my teg having that. that reminds me i need to get the car out and drive it. i hav't touched it in 2 weeks

That piece is a some sort of sensor that is connected from the intake manifold vacuum source towards the charcoal filter mounted on the firewall by the battery. I'm trying to remember if I connected mine. Your Y8 should have that too. Should be mounted by the injector harness. It may not look the same but should be the same purpose.

oh evap

yep :yes:
