Fuel leak at shut down, any thoughts?

Hi Guys, I'm pretty new to this truck an 02 7.3L, but I'm loving it!!!!!! BUTTTTT, it's leaking diesel from the back of the engine. At first I thought it was oil(my sniffer isn't so good) from a rear main seal, but now I'm sure it's diesel. I think it's only at shut down since I've put about 2K miles on her and am getting fine mpg, 18-20 on the highway.
I've searched the forum and seen the remarks about the fuel bowl leaking in to the valley but I don't appear to have fuel in the valley. Any ideas please...

Just had the same problem with my 97 7.3 turned out to be the water seperator/filter canistor initally had pin leak then finaly gave way. Apparently fuel will boil away from hot engine canistor is $167 AT DEALER WHOLESALE Price be careful pulling plastic center peice out it has left-hand thread its $75 if you break it heater assm is $67.50 DEALER WHOLESALE also dont cut the little blue hoses they are special high heat that cost $28 for all 4. You also have to fill canistor manualy to restart if you empty high pressure pump as i did. I kept leaving drops of leaking fuel in drivway and also smeling fuel until it finaly busted through enough to leave me stranded when it died had to have it towed home. Good luck

Hi Roger, Thanks for that advice I'll get up top and check when hot too see if I have the same issue.
I had a sunny day and got my butt out side to give it a good look over and flipped the drain. It is fuel coming from the Separator/Filter then leaking aft to the back of the motor. I had thought a leak in that area would result in a drip at the front of the motor.
