Point of interest.......All the carburated Mazda's had a return system to
bypass excess fuel to the tank !! Must have been a good reason...FWIW

You might be right, but I sure don't recall ever seeing this. I know that the later carbureted cars had charcoal canisters, and return lines from those back to the tank. I don't recall anything from a carb, though I never really messed with my 85 RX-7 carb (as hard as that may be to believe).

Rusty, Several makes and models had a banjo fitting with 2 tubes on it. One was about a 1/4 id and the return was about a .06 hole with a normal size line fitted externally. I had a friend that got the lines crossed and the mini pickup would run fine around town and at idle, but would "run out of gas" on the freeway. The truck had an electric fuel pump so when it died he would have to pull over for about 1/2 a minute and it would fill the float bowl and drive away normally. The crossed lines totally drove him nuts, until one day he asked me to fix it for him. I was stumped until I traced the fuel path. Changed the lines back and he never had another problem with it.
