Part number or name of part

[Ravenlunatic]

Does anyone know the name of the part or GM part number of the following part: it is located on the passenger side of the engine, under the injector cover. It looks like a diaphragm, and it has a 2 wire connector on top. There is a hose coming from the purge solenoid and another coming out the other side that looks like it vents to the outside.
Thanks!

I got it part number 12555984 its the evap emissions canister vacuum switch, $18.13 through the dealer. It will be here tomorrow hopefully it fixes my Service engine code P1441. That light has become very annoying.
