I got home today and my truck has a diesel leak at the bottom of the fuel filter. It seems to be coming from the drain fitting on the bottom of the filter. A spontaneous leak. Changed the filter about 2 months ago with no leaks but have one now. Tried to drain a little fuel by pushing up on the water drain thinking it might have something in it. I have not touched anything for about 2 months. Any ideas about the spontaneous leak?

Try exercising the drain valve.
They have been know to stick open a little, or vibrate open a bit.

I suggest that the leak might be from one of the rubber fuel lines, and appear to be from the filter.
Something to check.

 

Just to finish off the answer to my fuel leak at the fuel filter I bought a new sensor/drain from Dodge at the cost of $50.00 ??? Removed filter and installed new valve/sensor and the leak was worse. Did that about 3 times getting cut by the clamps on the boost hose and then bought a new filter and changed that, (the old one was 3 month's old, a NAPA filter), the leak was the threaded portion at the bottom of the filter. So now have 2 drain valves and a new filter (also from NAPA) and no leaks.
