@w3wilkes @madkawThanks for your feedback.
It is just from wich perspective you look at it.
We restore several 1969 production US cars and European cars, These cars come with tanks that have the connections like the tanks we produce. Also the cars produced for the Japanese market (including the Z432), the UK , Australia and the rest of the world came in this configuraton (without the vapor connections)
A lot of people I know in the US said that this configuration would fit them also, because they delete the vapor system.
For the US market cars we restore to a "as it left the factory"level, after the tanks are produced, we simply ad the connections and we have the tank the car came with when new.
Till now most orders came from the US, but also Japan (for a Z432) and the rest of the world.
I have a 1970 919 color 240Z I use as a daly driver, and this car I run with triple Mikuni's so I don't need the emission and vapor stuff at all on this car.
