i have a 2001 gmc 3500 crew cab 6.6diesel. i have fuel dripping from a line by the i think is called the fuel cooler under the gas tank, the leaking line seems to be right at the gray connetor that holds both the lines together.
i think its the return line that is leaking not the feed because the truck only leaks when running,, is it recommened that you splice in with a rubber hose. or do you have to replace with a gm new line, i herd to put the new line in you have to take the bed off.. is there a easier way.
any help would be great
