Emissions have not been an issue for me, and I live in the People's Republic of Kalifornia.
Had my Cruiser smogged last summer with the tank and dual filler. Smog tech didn't even look under the truck.
My '77 FJ40, however, is a different story...

Did you use OEM parts for your truck? or did you make them yourself?
A mixture of both, but tried to keep it as OEM as possible. Tank and filler are OEM, pump is aftermarket. Although, it doesn't matter if they don't look.
I believe those are the key components, due to venting, for emissions testing.
I built my own filler neck (simple Y, very common) but I'm not sure i'd pass an emissions test if needed.
I also fill the main tank with the sub tank, I dont have a direct line to the fuel rail, that modification probably wont fly either when testing.

I would not think anyone would have emission issues with an aux tank using an OEM tank and filler neck. Every test they could do with one tank would test the same if you ran dual tanks and filler necks.
I think in some areas, any non-factory emissions equipment is an automatic fail. I imagine it is up to how anal the judge is.
A dual tank would not effect emissions. The aux tanks vents the exact way as the main any tank pressure testing done the results would not change.
I don't have any first hand experience with it, but I have read about vehicles being failed on a visual inspection just by having an aftermarket air cleaner or even an intake resonator removed. I know things like aftermarket carburetors or EFI swaps can get failed immediately.
There's threads here about aftermarket cats failing visual, so an entire extra fuel tank without a CARB-certified aux-tank-evap-canister that doesn't exist might be valid reason to fail an emissions inspection. I live in a free state so I don't care either way, just speculating.
