Name this Part!

On my 2006, down below the brake master cylinder, there is a black plastic
device with small green screw on cap facing forward, On the back there is a electrical pigtail, and 2 hoses coming from the main portion, 1 goes to the top of the air box, on top of engine, Vacuum line I think, or Vent ? the other line I think goes down the frame and my guess is back to the fuel tank. My concern
is when the engine is running I heard what sounded like a vacuum leak,
running my fingers around the top circular top of this device, I found the air leak
This looks like it may contain a round diapragm, Any ideas on what it is and what it does, and If I need to replace it,
I have no check engine lights on as of yet.


thanks

David

It's part of your emmisions, its a vacuum solenoid valve. It runs from your fuel tank vent to your engine. Iirc, it sucks the built up vapors in the tank and deposits them safely into the engine, avoiding ignition...
