What is this thing?

[pcfnet]

I was trying to do a boost leak test but the system cannot hold the pressure at all. I can hear some leak near the split hose near the red circle. I also smell fuel when I put my head near it. Can anyone tell me what king of thing is this?

It's cruise control vacuum pump

It should not be connected to any engine vacuum line.

Thanks Des, is this item 28?

my idle is not too smooth could this be a reason if there's a leak. I can smell a bit of fuel when close to the hose...

Item 28 it's a idle stabilizer valve and all hoses around it should be leak free

To do the boos leak test I would use the hose from the turbocharger where it's boosting to intercooler.
