Thanks for all the good info but even after I took the bowl out and looked for cracks and replaced all the O rings and deleted the big sensor on the back and replaced all hoses i still have fuel on top of the motor. Looked with a mirror and can't see any leaks from anywhere. What the heck? Looked all over the motor and I got nothing jumping out at me that could be where it's coming from. Any more thoughts?

My fuel pump was leaking from the weep hole on the bottom passenger side. You could watch it drip with a mirror.

It's a federal truck. Replaced all prints on fuel bowl and checked for cracks. Replaced both banjo bolt gaskets. Cleaned up the valley and after a while of driving I had so more puddling, but it's not dripping on the ground or making my truck stink like fuel inside the cab anymore. Got a mirror out and can't find any drips. Ran hard for a minute then parked and looked again and still can't see a drip with a mirror. But I'll look again tomorrow after driving home from work. It's weird that the leak lessoned after replacing the banjo gaskets but didn't stop....could it be leaking from under the pump? Like the oring has craped out?

Just from my experience, I would check those soft lines which thread into the FPR assembly (near HPOP) Mine were brittle and cracking. I would focus around your fuel pump and hard lines too.
I didnt realize how badly my truck was leaking until I tore everything out and realized my hoses, fuelpump and viton sleeves on the fuel hard line were all leaking!

Well I finally got around to replacing my fuel pump with the one from adrenaline and now more fuel on top of my motor! Easy fix, only took 3 hours and scraped up knuckles but it's all good now. Thanks to all for the input!!!!
I took it to a guy to find the leak cause I was tired of detaching and he said the pump was cracked, and to just replace it myself so I did. Never heard that before.
