GM has two designs of fuel systems, returned or returnless. The difference is in the fuel pressure regulator, either mounted on the fuel rail or on top of the fuel pump.

The most common fuel system is the returned style. If installing this intake manifold on a returnless system, there is no modification of the vacuum routing necessary.

Adding the vacuum source for the fuel pressure regulator can be done in two ways. You could add a tee fitting into the PCV hose. Or on most models, there is an unused vacuum port on the passenger side of the intake. is now offering a GM Intake Manifold 17113697 replacement that has been modified to work with vehicles that have an EGR tube feature
