It is located under the plastic intake manifold plenum. It is an internal design because it draws it's vacuum from within the plenum. New answer: A 1995 is TBI (THROTTLE BODY INJECTION)

tHE REGULATOR WILL BE FOUND ONTOP OF THE TBI. HOUSING JUST BEHIND THE 2 INJECTORS.

only the vortec engines have it under the upper intake plenuem.
