Help identifying vacuum hose

Post by **Ludermilch** » 04 Mar 2015, 20:21

I was inspecting all my hoses tonight and noticed a loose vacuum hose. When I grabbed it to reconnect it to what I thought was it's home the hose fell and now I have no idea where the other end goes.

It's the black plastic hose in the center of the photo, just below the throttle. The rubber hose is 8"and I could not find where it connected to. Looked over a post detailing with photos many of the hoses without much luck.

Thank you.

The first photo I posted was too far away. It isn't the PCV hose, I'm familiar with that line. This is a 4mm/3.5mm vacuum line that seems to go nowhere. It's directly below the throttle body.

Here is a close photo.

I am looking into silicone hoses to replace most of not everything.

Looks like it's part of the long PCV hose as mentioned.

It goes from a nipple on the end of the intake manifold, to the PTC. Looks like it broke on the middle. Don't use silicone on that one, it will get all "sweaty" from oil fumes, use rubber.
