I am replacing my fuel injector "Spider" out of my 4.3L vortec v6 Sonoma and can't find any diagrams on routing of the injector lines. I pulled my old injector out thinking that there was a routing diagram with the new injector but there wasn't and I can't find anything on this. Help please.
Thanks

Hello,

You will need to check out the diagrams below and check out how they go which is just into the port the injector is closest to once installed into the intake manifold.

Check out the diagrams (Below)

Let us know what happens and please upload pictures or videos of the problem.

Cheers

Yes, do the lines just go straight out to each hole, what I mean is like the injector line closest to the firewall on the passenger side goes to the cylinder hole closet to the firewall on the passenger side right, not in the middle cylinder or anything.
Thanks for the help

Yes the injectors go straight into the closet hole you should be fine. You can take a picture of the job once the injector is in so I can check it for you?

Because other videos say on the passenger side you have to put the middle injector to the # 6 cylinder and the far back injector put in the # 4 cylinder. Can you confirm?
