Good Day, I seem to have a fuel leak in may 3gm30f diesel under the injector retainer. At first I thought that it was in the fuel line as it drips off the nut but have determined that it is coming from above. It is not from the return line. Does this mean that a have a bad washer or something worse? I thought that a leak here would be highly pressurized and easy to see but only seeing/feeling fuel easily after it accumulates enough to drip off the fuel line nut. Any thoughts on what I'm seeing would be appreciated.
