I have a dual tank system and the spare tank is disconnected. And the main tank lines are all rigged weird. I cant find a diagram for the fuel lines and I need to figure out how there set up so I may repair the lines

You should be able to get a diagram from a dealer. Or check repair manuals for one. You could probably Google "diagram for dual tank fuel line on GMC truck(add the year), you should come up with some answers.
