Fuel Leak- HELP

Hello, I bought a 1995 7.3 on Saturday and it has a slow fuel leak. Appears to be coming from the back side of the block and running down into the transmission bell housing. Any common things to check, ideas, or help in general would be very appreciated. I would like to diagnose the problem and maybe fix it tomorrow. I just need some advice on where to start. Thanks in advance for the help.

If it's dripping around the bell housing it is most likely coming out of the back of the valley on top of the engine. Take of the plastic cover, get a flashlight and a mirror and start hunting around the fuel filter housing and lift pump with the engine running.

Yes, lots of places to leak on top of the engine! When enough fuel gets in the valley, it will drain down the passenger side rear of the engine. If the valley is dry, look at the back of the heads where the supply lines go into the heads. There are rubber seals there that can be replaced (kind of a pain in some cases to replace). Cheers!

Pay close attention to the blue fuel hoses. The po of my rig changes the pump and fuel filter but left the old hoses, they are cracking and leading very slight.
