replacement procedure for a spider injector

Hello, I'm Danny.

Here is the information you requested. You will need to remove the upper intake manifold to change the spider injection system. Here is a tutorial showing how to change intake manifold gaskets:

I've attached picture steps below on how to change the fuel injection (spider) system on your vehicle. I've circled the unit in red. I've also attached a picture below of the Delphi brand upgrade which is supposed to work even better than the factory injection unit. Hope this helps and thanks for using 2CarPros.
