Rear Valley Fuel Leak

[ff_cspires]

Hey everyone just need some help pin pointing a fuel leak on my 2003 7.3 F-250 with 98,500 miles. I just bought the truck 2 months ago so I'm still working on tracking down all the things the previous owner left off with for the maintenance. Right now the leak isn't to bad its only filling up the last section of the valley but I'm not leaving puddles or trails of fuel on the ground like some guys are talking about with leaks from the drain valve o-rings or the notorious fuel line clamp rub. It looks like there is fuel residue the fuel line from the bowl to the right side of the valley. Are there any o-rings back around that line connecting to the cylinder?? The front and middle of my valley are bone dry. I can make my way around the maintenance of a 7.3 pretty well but when I get into the little tedious things like this I'm still learning. Any Ideas or info would be great.

If not rubbed through maybe the fitting itself is leaking? Not a lot of places fuel leaks at the back of the motor other than there.... How about the plug on the drivers head, in the back opposite of the clip & line on the pass side?

Well I will take a look tomorrow when I get off work and I'm home with the truck. I just found and interesting write up about the fuel sleeves on those lines PITA to work on due to the placement but very much doable. So it looks like I will be replacing sleeves and at that point might as well rebuild the fuel bowl while I'm there since its only $24 for all the sleeves and o-rings. Thanks for the help I'll check out the driver side too.

Well got the new fuel line sleeves and o-rings installed last week and the valley has been bone dry ever since. The sleeve on the back of the passenger cylinder head was pretty much nonexistent once I got the line off. No rubbing issues around the clamps.

Well after a couple weeks fuel is starting to com back to the valley looks like its time to tear it out again and replace the fuel line. the only place its puddling fuel is right below the clamp so I'm guessing the line now has a small pin hole. so back to dealing with the pain in the butt rear nut!
