on the 5.7Literl engine its under the black plastic intake plenum. The intake is two pieces. Its between the two pieces.
Can you show me on a video
The 1974 Chevy truck has a mechanical fuel pump with a built in pressure regulator.
It controls / regulates the fuel pressure.
do you have TBI ?
It is in the throttle body.
if you have throtle body injection the regulator should be right on the throttle body it self.On a 1996 Chevy truck there is not a throttle body , the regulator is under the upper plenum(the plastic piece that sits on the intake)also the injectors are under there as well all 8 or 6 witch ever motor you have.
possibly a fuel regulator or bad valve
It is in the fuel tank.
It is inside the upper intake manifold.
The mechanical fuel pump regulates the fuel pressure. This truck is not fuel injected. It has a carburetor.
under the upper intake manifold.
Check fuel pressure, fuel pressure regulator.
Correction: It is a 1995 Chevy Corsica. Not a 1996.
