So I have searched but could not find an answer on what this part is. On my car I noticed oil around this connector and it seems kinda loose fitted , maybe with time and oil it lost its rubber quality.

 

Appears to be part of the secondary air injection system piping.

 

Part of the vacuum hose for SAI and Fuel pressure sensor.

If you look at my 'supercharger and throttle body elbow removal advise' thread, at the bottom there is a parts list with that part #.

Local autoparts stores do sell just the connector pieces if you want to look around. Not sure if they will have that size and angle, though.

EDIT: I would grab a flashlight and look deeper into the valley there. Any signs of oil may point to a bigger issue.

 

The only time I had anything leak out of that was methanol when running on the track. A couple of zip ties solved
that.

 

Thanks for advise guys! I might try the zip tie idea first.
Any idea why oily there? It seems oil was coming out of that tube, good amount of oil there when I peeked in..
