Internal to the throttle body. It's the roundish "bump" in the TB cast between the injectors.

Depends on which fuel system your Blazer has. If it's TBI, it's on the back side of the throttle body hanging down near where the fuel lines enter.
If it's the Vortec system, it's inside the upper plenum.
