ok so i have an evap emissions code and it wont stay off when ever i clear it ive looked at everything new gas cap vaccum lines everything cant find a leak so i have a part that i got from the previous owner. it was never put on due to couldnt find out where it is on the truck i have a 02 blazer ls 4.3 vortec 4x4 i have this part but dont know where it goes all i know is its some kind of evap emissions valve. it is an original GM part and i do have a part number if someone could cross reference or if theyve replaced it before or just plain old know what it is what its for or what it does i need to get inspected and the light wont stay off and i figured well i have this part i might as well put it on and see if it works here is the part number GM#25658328

The vent solenoid is a good possibility.
