How do I get to the fuel lines to replace them?

[gdtreece]

I have a 1986 Ford 4610 diesel, 3 cyl. It has a fuel leak, which also sucks air into the fuel line and floods the fuel pump with air and makes is surge or not work at all. I have tried to follow the fuel lines to locate leaks, but there is too much covering the area. How do I removed the cover on the tractor so I can see the fuel lines to replace them (at least all the rubber lines)?
