[AT] Massey Ferguson 431 fuel leaks

[Howard Rawls]

Hey Guys, my Massey Ferguson 431 Diesel has developed some fuel system leaks. I replaced the return line that goes to the top of the tank and that doesn't leak anymore, but now I see fuel seeping out of the line that comes out of the bottom/side of the fuel tank. These lines are "braided" type lines, but I wonder if it is ok to replace them with non-braided lines? I don't have a shop manual, so I don't know which lines might have pressure on them. Maybe there is a fuel pump inside the tank? Why are these lines leaking after only 6 years of service? On my other tractors the fuel lines seem to last forever ;-) . Anyway, this MF 431 is a great tractor and this is my first real problem since buying it new in 2006, so i'm not complaining. All comments are much appreciated, thanks!
