Our CAT 420 f, is leaking fuel from front corner of machine. I follow the 2 fuel hoses that go to front and dive down somewhere under the radiator. Not a great area to see into. Does anybody know how to access a diagram of fuel system so I can take some of the educated guesswork out of the mystery leak?

Oh damn, my bad. JWJ01898. There is a pair of fuel lines that run to the front and disappear under the radiators. That is the area of leak.

That's it! Thank you. A picture is worth a thousand words and in this case saved time.
