just cap it at the tank
it is absolutely stupid to think of any need for recirculating fuel in a carb system with a pressure regulated pump (as are 99.9% of all carb-car fuel puump systems)
- just install a simple psi regulator at 2-3 psi before the carbs, , and the simple fuel pump (like a Facet) will just stop sending more fuel
- no need to run it back to the tank - that's just dumb!

I disagree
a re-circulatory system keeps fuel cooler
(the fuel isn't sitting in the lines over the engine absorbing heat)
makes more horsepower as a result
and is better over all (even combats vapor lock)
putting fresh cool fuel into the carb bowl (versus fuel sitting in the line heat soaking above the engine) Does help combat bowl boiling.
all modern cars (and even porsche when it designed the 914) use recirculatory systems. They are used on millions of factory designed current vehicles
even on carbs it is still better than non circulatulatory systems
it is better
only a little better
but still better
not accurate to call a superior design stupid or dumb...
