    It on the drivers side fuel rail under the beauty cover, Its about as round as a 50cent peice with a small vacume line connected to it. A spring clip holds it in, When you pull it out make sure the small o-ring comes out with it, it could fall down inside the fuel rail, or if it stays inside the rail you will never get the new one to seat properly.

    hundojoe is right. I was thinking fuel filter. Call me sh*t for brains.
