Does a 1990 chevy truck have a fuel regulator, 5.7 efi? if so where is it located?

Yes. The fuel pressure regulator is mounted on the throttle body.

On the side of throttle body you’ll see a metal cover protruding out held on by two screws. Under this cover is the fuel pressure regulator spring and diaphram.
