fuel leak in 7420

Colter Dunagan Hello out there. im having trouble locating the desiel leak on our 4x4 7420 john deere, any one dealt with this before or had the same problem? It looks like it just seeping out of the lines themselves. It leaks quite a bit of fuel when its running, but i cant seem to find a single source for the leak. Any help would be much obliged.
John Heine Well bud it is the sending unit that is leaking maybe....
ross I would replace all of the rubber fuel lines. I have seen this problem quite a bit. If you can just replace with regular rubber fuel line. The line from the dealership usually only lasts a couple of years.
