If I  plumb the breather into the top of the fuel cell, then attach a foot of 
 braided line and route it below the bottom of the cell, like an inverted 
"J",  then the opening would be above the fuel level in the event of a  
rollover. 
 Is that sufficient for rollover safety, or do I need to do  something more?

Hi DickJ
 
I ran 1/2" aluminum fuel line tubing completely around the fuel cell. I  went 
down the side, around the bottom, up the other side, across the top and  down 
the same side I started on. The tube exits out the bottom of the belly pan.  
I figured no matter how I may end up, excluding "lawn jarted" into the salt, 
I'd  be cool. 
 
There are also "tip over" valves but they aren't cheap compared to aluminum  
tubing. I'm not sure "tip over" valves are legal as they have a ball check 
that  may not be effective if you are laying on your side.
 
I don't agree that you need a huge vent line equal to the fuel feeds. Air  
moves much, much easier than gas. 
 
Big vent lines on dry sump oil tanks are another story, go big or go home!  
LOL
