small fuel leak...

hey guys, got a small fuel leak nothing ceazy but annoying. i got a 99 7.3 and when i wake up in the am there is a fuel spot about the size of a half dollar under my engine. did some looking round on the bottom and it looks as if something is dripping onto where my started meets my tranny and if falls from there. so i did some looking on the top and there was fuel/liquid in my valley. so i cleaned all the fuel out the valley and wiped around the started and going to check it again in the am. did some research and seems the diesel fuel drain o ring could be the culprit? any ideas? thanks

yeah the o-rings in the drain valve on the back of the filter bowl dry out and leak, cheap and easy to replace. just get the o-rings unless the valve is broke.
