We got lumbered with the same emissions set up here from 1976. It can legally be removed as with modern fuels, it does nothing.
Why does the smog pump do nothing with modern fuels?
There was a few chemicals in fuels that were made in the leaded days that this system 'managed' but these chemicals have been removed from the fuels that are available today.
Oh right. I thought the smog pump injected air into the exhaust ports to provide an afterburning effect to the exhaust gas to reduce hydrocarbon emissions caused by unburnt fuel.
