Making the fuel tank, part 2

So I ran into an issue today when welding the fuel tank, namely the placement of the fuel pickup bung.  It ended up too close to the main box, and I melted the bung trying to weld in the box.  Oops.  We cut it off, and welded a new one on the back of the tank instead, which should be okay - it just necessitates slightly different fuel routing.
Nope, not good enough at welding to weld that yet...
What I ended up doing:
Not pretty, but it works.
What's left?  I need the sight line tubes to be made in the lathe, and then those need to be welded to the filler neck.  The filler neck then needs to be welded to the main box, and bungs for the check valve and return need to be welded in.  Finally, mounting tabs need to be welded on.  All of this should be done before the end of the week.
