It is a press fit, but not a real tight one. If the intake is off you can just tap it forward. If not, try grabbing it with a Vice Grip and tapping the VG forward.

Right! Of course, GM has a special tool to remove it, but I just tapped mine out. Came out easily.

Be sure to re-install the tube connector in the correction direction - grooved end toward engine.
