Pass smog on t2 with Na fuel pump?
Anybody have experience with passing smog on a t2 with a Na fuel pump? Bought a "t2" pump which ended up being a no turbo. Figured would lower hc but worrying about raising nox

It won't affect the mixture since an na pump can easily supply enough fuel at smog test speeds. The pressure regulator will keep it running as the ecu intended.
