I have developed a fuel leak that drips from a point about a foot inside the drivers side directly below the tank.  Anyone have any ideas on this? It started a while back but doesn't seem to be getting any worse. I was parked full time in Tyler Texas through the winter of 16/17 and temp dropped into the low 20's a couple of times.  On those occasions I heard a noise that sounded like someone hitting the tank with a rubber mallet, I assumed it was caused by cold contraction of the air since I didn't have but about half a tank of fuel.  Wondering if I might have popped a weld.
