fuel leak in valley

My 96 7.3 has a fuel leak that fills the valley and drips down in back of engine and bell housing. Not sure where the leak is coming from.
In the picture, there are 2 circular dome topped things that have fuel all over them. What are they and what is their purpose?
I've done a search and have not come up with an answer.
Any ideas where the leak is coming from?
Thanks.......Dennis

That's the fuel pump. It could be leaking from there or anywhere on the lines, fuel filter bowl, or fuel pressure regulator (on the side of fuel bowl.

the fuel pump has a weap hole on the bottom of it, when it goes bad it'll start leaking out of it. i replaced mine at 260k. Not saying thats your problem but its a start. use a rag to dry as much of the valley as you can, get a good flashlight or shoplight shinin down over the valley and have someone else start the truck. check for leaks that way.

it looks like you need to do it any way!!!! nasty 7.3!!!! i would lift the fuel bowl(2 1/2 bolts) remove all lines and get hem replaced,ford has a kit with 3 blue fuel lines that arnt much at all,replace the tandem lifter pump and clean her out real good....also,when you have your fuel bowl out,disasemble and clean it...the regulator screen and all,the water drain has new o-rings that can be replaced also...and if you really wanna do it good,go ahead and replace all your hpop o-rings to,whilst you have everything removed....ford sells this kit also,even comes with a cute lil bottle of loc-tite...good luck!!!!!

When I had that problem on my truck a month ago it was leaking from here, and it was the fuel regulator.... good luck.
