Not sure if you are referring to the return lines from the injectors or not. Check the attached image. If we both are talking about the same line, it will be in sections, since it is connecting to the return ports. It appears that these lines are not pressurized and thus you could replace it with a length of fuel line. As for the how to, and what to expect etc. you can download the service manual [http://www.keepandshare.com/doc/3327735/john-deere-tractor-compact-utility-670-770-790-870-970-1070-tm1470-010200-pdf-december-4-2011-9?da=y|from here.] Hope this helps, good luck.
