I’m assuming that like so many of the repro parts that are advertised (many incorrectly) for “Firebird-Camaro” that the repro tank is aimed at the Camaro. If so, what did the Camaro use? Or did they have the vent, or vented cap? Also, it seems like the hole in the vented cap is so tiny that not much gas could escape.?? Could that be the case? Does gas escape out the neck vent tube under hard acceleration? Still not sure which way to go.
