Previous owner did a number on the fuel system. Which I'm trying to straighten out. Looking on the internet, it looks that the heads are supposed to have 2 ports for fuel lines on each head. But this motor only has 1 on each head. One at the front of the driver's side and then one in the back on the passenger. The fuel bowl is compleatly gone And it's got some janky fuel line inline filter set up crossing all the lines together.
The line setup to the cylinder heads that you describe is correct for a 99-03 7.3L. As for the missing fuel bowl, can't help without seeing what's there.

As others have said, you are describing a factory set up for a super duty. Snap a few pictures of the engine valley and look under the truck for a filter set up.
Factory fuel pump is directly below the drivers door on the inside of the frame rail.
Here is a Pic from Facebook land so yall can see what he's working with. It's quiet the setup. Looks like there using a ball valve for fuel pressure regulator. Then it goes from ball valve back to the factory return line. lol I'd tear every bit out and start over.

That is actually a high pressure needle valve. They are often used for flow control because of the fine adjustment they provide. I like using them as throttle valves on natural gas oilfield engines in situations where there just isn't a lot of fuel gas available. I can fine tune the mix to run a little on the lean side to conserve fuel. Also good for slowing an engine that's really just to damn big for the job. I can set the governor to hold the butterfly closed, then use the idle screw to just crack it open a hair. The needle valve lets me bring the fuel flow much lower than a ball valve ever would but still have the option of opening her up when needed. So technically it is capable of kinda working as a regulator, but still janky AF and several better easier and simpler ways to to do the job. Did this used to be a farm truck? I see farmer engineering written all over this setup.
