Make a tank shape on a mold, with one side missing, and make the missing
side as a cover. Alternatively you can use a consumable mold and simply
make an access hole large enough to do the following:

Bond/Epoxy some flat plate aluminum stock. At least 3/16 inch thick..
depending on the size of the fittings, but you want to engage at least 3
threads or so on the fitting.

Rough up the aluminum stock (at least 1" square area for each fitting
penetration). Overlay with BID to sandwich the stock. Drill, Tap,
Install fitting.

Bond/seal the tank with something fuel resistant. Jeffco comes to mind.
It also is prudent to make the tank with fuel resistant epoxy in the
first place, particularly alcohol resistant since that seems to be the
future of Mogas.
