I've been having problems with my 2000 Chevy 1500 4x4 5.3L stalling. So today I went out to replace the fuel pressure regulator hoping that would be the problem. The only issue is a small washer slipped of the end of the regulator and rolled into the fuel rail. Now I'm not a great mechanic and i'm not a bad one either. I've never done anything like this before. Does anyone have any diagrams, pictures, or videos? If I can see it I can do it but right now I'm lost and I can't be without my truck for long.

Thank you,
