And here is the finished product.

I stole the hose and commercial nozzle from my previous filler system.
The hook filler cap allows me to get a good seal just using my hand to
tighten, as well as a way to lift the whole tank into my pickup.

The second hardest part of the project was passing the leak test. Since
I do most of my welding outside to avoid fumes, it is easy to get a very
slight invisible "micro-porosity" in parts of the weld. 50 psi of air finds all
of those. Small leaks are not crucial as all welds are above the fuel line,
but I eliminated all leaks anyway. I used a MIG welder (Hobart Ironman 210).
That is why some of my welds are as pretty as they could be (big).

Photo M shows the nozzle holder and drip catcher. This nozzle is amazingly
leak-free. Photo N shows my sight guage and guard. The fuel level will be
even more visible when I switch to red diesel.
