Cant find my diesel leak

So I have had this leak for a while and I finally got around to putting new Orings in the separator valve which seems to be what is usually the problem. I still have the leak. I cant for the life of me find where it is coming from, I just see a drop hit the puddle in the valley every so often. I am looking for a write up on everything in the fuel bowl that can leak so I can check things one by one and go thru it and make it right. Any thoughts are very welcome too. Thanks

read another possible location, and thats the fuel "hard" line, running from left side fuel bowl, to back passenger side head. That rail, where it goes under the plenum, i guess it rubs on something, and overtime, develops a hole.

if you have an after market fuel filter (not a ford filter) it can leak out of the o-ring. but sounds like it is a slower leak. i would check all fuel lines and anything fuel related. i know you can put dye in the oil to find the leak, maybe do that with your fuel and use a black light to find it?

Its dripping worse now. I think I will take the valve off again and make sure its seated right. I do have an aftermarket filter, I will try a new one. When I look it looks like the diesel is dripping from the electric plug, does that come off and have o rings like the separator valve? Also the diesel is dripping from the weep hole on the bottom of the motor, looks like its coming out, is that a possibility?
