Diesel leak in valley

I have a 6 speed 7.3 and I literally just did the fuel bowl rebuild because everywhere I looked that's what people said it was, well wasn't that. Any idea what else could be leaking into the valley and then all the way to the ground? Need help this is really annoying me now

Mine was the water/fuel separator valve. Not a solid leak but it was seeping enough to puddle up in the valley and eventually leak to the ground. Dieselorings.com had everything I needed.

Check the fuel line to the passenger side head. Clamp rubbed through the steel line under the clamp. Common on the 7.3. Took me a while to find mine.

How were u able to pin point where it was? Cause it seems like it could be a lot of different things around the fuel bowl

Kept cleaning out the valley and parking on inclines nose down and up. Could never really get a visual with a 100% certainty where it was coming from and went for it. When you get down to it there aren't many places in the valley containing fuel. Only about an hour to so to.

to back stang up.....when I rebuilt my fuel bowl....I read about the possibility of the passenger side fuel line rubbing on here. I checked and at 116000 miles you could see where all the anodized coating had been rubbed off mine. A few miles down the road and I would have had a leak as well. I fixed mine...I hope you find yours.

I had the same problem with the fuel line rubbing open. There is a bracket right below the x on the pass side. It will rub a nice opening in it. Good way to tell is try and move the fuel line while the pump is running in the koeo position and watch the little bracket if you ser fuel coming out it will run like mad if you kove the line rough in the bracket.

I think I fixed the fuel leak, but now it's an oil leak from the HPOP to what looks like the valve cover on the driver side, it's leaking from the line at the top of the valve cover

Thats most likely the oring in the fitting. You can pop the fitting with a bicycle spoke tool if you have one and take the fitting out of the head and replace the oring. I would get the oring kits for the hpop lines before those blow out too. That will empty your oil out quick.
