That is the round thing on the top rear of the TBI. The thing that looks like a carburetor.
On a 1994 Chevy C1500 5.0 V8 it is the top valve with a black cover next to the coolant resivoir
its part of the fuel rail and has vaccume line connected to it
It is inside the upper intake manifold. To get to it you must remove the throttle body, upper intake manifold, and several electrical lines and fuel lines.
