In the mornings when I start my truck the temps have been just below freezing and I am noticing a fuel leak. It is dripping off the back of the engine down the back side of the oil pan. I checked to see if it was leaking from the drain valve but that does not seem to be where it is leaking from. Any thoughts as to what might be causing this? After the truck has been running it does not seem to leak any more until the next day when I start it cold.
