fuel leak

I have fuel leaking down the back side of the drivers side head. all the fuel connections i can see are not leaking. I have replaced the fuel drain valve. There is also fuel in the valley. Can someone point me in the right direction please, thanks Chris.

ok, I dried up the valley and started it again. the valley stayed dry. All I can see is it is coming from somewhere behind where the exhaust tube goes in to the turbo.

passenger side head maybe were it connects to the head? Also there is a clamp on the passenger side head that can wear a hole in the line.
Have you pulled any lines off with out replacing the seals?

Ok I'm totally stumped. Yesterday I removed and rebuilt the fuel bowl. New valve and all o-rings. Gasoila sealant on all threads. also Gasoila on fittings into front of heads. This did cut the leak in half but still dripping.
any ideas?
oh I have a regulated return, can anyone tell me why the return on the bowl is caped? ( i didn't install it ) came with the truck. thanks.
