I've mentioned it around quite a few times, and I don't think anyone has even acknowledge it yet, so, I'm posting it as a bug.

All vehicle types except the fluid wagon can have a grid. I don't know if the grid isn't being added at all, or if you simply can't interact with it, but right now, the fluid wagon has no usable equipment grid.

it is of type "item-with-entity-data" like the other vehicles, so it does sugest it should be able to have a grid, but, you can't use it.

Can you give me a mod that adds equipment grids to trains for testing? It should support it simply the GUI doesn't show it right now.

Yes.

My vehicle equipment mod should add a grid (and related equipment to put in that grid) to all existing base game vehicles.
you'll need my library too

It does add the tag to add a grid to the fluid wagon, I just haven't been able to interact with it at all.

Ok, it's now fixed for the next version of 0.15. The GUI will show the grid.
