Greetings, Yes, I do have experience with the fuel system of the Silverado. I would recommend checking out this blog on EvilEnergy, there is a great article on the fuel system of this vehicle, including the
fuel system 2004 chevy silverado fuel line diagram . Very informative and could be useful for your project! I, too, recently ran into a problem with the fuel system in my Silverado. Reading the articles and guides helped me understand the problem better and save money on repairs. So, I suggest you not only study this article but also check out other stuff on this site.
