2002 F550 7.3L leaking ...
I have done my searches here on the oil leaks, etc. I still need some suggestions please.
I have degreased the motors.
I am running her and looking over the top of the motor for fluid leaks on or near the intake mainfold, valley, etc.
The fluid, I thought it was oil, ends up leaking out the bottom, making you think it is the rear seal, but I have read the threads on why this could be coming for the valley drain off.
When I was wiping some resude from the steam clean, I noticed that I had what seemed like clean diesel coming from under the black top/cap of this:

Does this make any sense? Sorry for the dumb questions, been a Ford guy since 1965 Mustang, but always gas motors.. Thanks in advance for any feedback.

Welcome to FTE.
That is your fuel filter and the cap can leak. It happened to me before, I bought a new filter and changed the o-ring and filter. Make sure the gasket bevel is facing the correct way.
EDIT: Good catch Matt, I didn't even notice that.

Black top cap? The plastic 5 inch diameter one with the hex nut molded in? That would be the fuel filter cap, which would make sense for what you found leaking.... They have large o-ring that can be a leaker. Don't ask me how I know, but they can leak A LOT of fuel. I'd advise reseating the cap. You'll want to releave the pressure in the fuel bowl first by opening and closing the drain valve, about a half second open is more than enough. The drain valve is yellow and located at the bottom of the fuel bowl, passenger side. Take the lid off and inspect the o-ring for tears etc. If it looks good, wet it with fuel and reinstall the lid. Get it good and snug, but don't over tighten it, o-rings don't like that....
I've not dealt with that style of cap, but I suspect the o-ring to be like a stock cap. The stock o-ring is triangular and goes on the opposite of how you think it should...Just wish I could remember which way that was...If the leak persists, try flipping the o-ring.
Good luck with it.

First of all I grabbed that pic from another post to help id the black topped device.
You could eat out of my engine compartment, so that was not my truck.
Like I said, as I was wiping up to check for leaks, my hand came up with fluid when rubbing against the black round cap like area.
So should I replace this filter and does that come with a new o-ring?
Thanks in advance, you guys are great, and I want to stop that dripping all over my driveway...

Thanks guys, this interactive feedback is priceless.
I will take a closer look at the filter, take the suggestions, and see if I can re-seal it. I would have sworn the fluid was oil, but one thing at a time...

Thanks to everyone for your advice...
Well I climbed on top on the motor so I could see what the heck was going on.
Our truck is a Super Duty 6x6 and sits up pretty high.
I found a leaky fuel filter seal and the yellow fuel line connector was also loose.
I installed a new filter, seal and o-ring, tighten the line and she purrs like a kitten.
After test the valley was dry.
Now where is the oil going. This rig has only 70,000 mostly freeway miles yet it seems to need oil replenishment too often.
Thanks again for the great feedback.

Still a leaker.. Moving back to hpop
I purchased the o-ring kit for the Hpop since I still have a leak with oil in the valley.
Sorry to be asking such a silly question... How do the oil lines come off of their connector on the hpop?
Thanks in advance for your help, I need to get this shored up..
