How do I replace the fuel lines in a weed eater? - diagram of a weed eater

A friend gave me a lawn mower with rotted fuel lines, but I know free gas and got half of the line and fuel filter came with the mixture, which I already bought kit for the fuel line, the different sizes or line and a filter. But I have no idea what line of carbohydrates, I remain in the fuel filter and is the shortest line, usually when I make repairs, and a diagram of how the configuration, but initially it was a little hard to do, if the lines are not in the first place. And if I return the 2 lines?
