Good catch - I didn't think of that! As the second tank is
filling, the air on top of the fuel needs to go somewhere. I don't
think you'd want to plug the original tank's vent hose though, I think
it would need to vent as well?
Some (many?) fuel cells come with a vent fitting pre-installed (or
it would be fairly easy to add one), so it may be possible to simply
run a vent line from the fuel cell back to the main tank, or back to
the filler neck, or simply T into the original tank's vent line. I
suppose that vent line technically could just hang out in the breeze
(with a check valve or filter on the end) as long as it was above the
top of both tanks, but then you will have gas fumes coming out the end
whenever you fill up, which may be problematic...
