Help identifying a vacuum sensor (1 Viewer)

[polloelastico]

I'm replacing some dry vacuum lines and when replacing the line on this sensor on the manifold I noticed it was a bit loose. Now, it can't have backed itself out I assume, so I'm a) not sure why it was threaded in loosely and b) thinking I should seat it snugly and c) wondering exactly what it is -- I've looked at the under hood diagram and it's not clear that it's on there.

It's the small hose in the picture on the bottom.

Thanks,

Ah, I think I've discovered it's a "Gas Filter" Part 90917-11022

Correct your gas filter is supposed to screw in the intake at that spot and then then small line connects to it.

Ah jeez, I think I see what was done. That looks to me like a the non-OEM part and also the wrong size, so a bunch of grey RTV(?) was used to make it fit. So now I need to remove that AND that RTV without any falling into the intake. What do you think the odds of that happening are? I could leave it, it's not a great fit but I think it's not leaking. I really don't want to pull the intake anytime soon, not for just that.

^^^^^
It's not even a 'part'. Someone took the smaller hose, stuffed it inside a larger hose and stuffed that (replete with silicone) into the threaded boss where the actual 'part' (gas filter) is supposed to go.

I wouldn't worry about a small amount of RTV going down the intake. It won't hurt anything. At worst...enter a cylinder where it will take a swift ride out an exhaust port. You don't want anything HARD going into the intake, silicone is of no concern.

New part is ordered, I'll have that sorted soon enough. Thanks everyone!
