Overflow fuel line leaks

I have been trying to get the overflow line on my 674 diesel to stop leaking.I just bought new washers and they still leak.Any suggestions would be helpful. Thank-you.Richard

Hi Richard, I assume you are talking about the return line on top of the injectors? Only solution is to replace complete return line. The older ones had a braided flex line, the newer ones have a composite material. They always leaked where the braid was joined to the fitting that was connected to the injector. Also would leak more in cooler weather.
