This may be a long shot to put in here, but I am running into a brick wall. I am trying to find the fuel vapor tube/vent for the midship 22 gallon tank on a chassis cab. Here's the best picture I have of it - it's not great, but it plugs into the cross tube that connects to the two rollover valves on top of the tank (I have that tube, it is part 5032258AB), it tucks down on the passenger side of the tank and then flips up into the filter that attaches to the bottom of the crossmember.

I am not positive if it is just the tube, or if it comes with the filter on the end. I do know it's not part number 68164876AA - that is just the little filter canister. I think it is part 2 in the diagram below on TechAuthority, but I have yet to find a parts screen on TA that doesn't have that line greyed out with no part number.

The other possibility is 52029544AA, but I am pretty skeptical about that because all of the diagrams (it's #10 in the diagram above) show it as being the shape of the rear tank hose/vent, which is much bigger than what's needed for the midship tank.
This is the only part I can't identify for this project, and while I could hack something together I'd rather find the right tube/vent.
Much appreciated if anyone has any insight.
