It just depends on what we are working on. Some cars have both, like my Chevelle for instance. My Firebird only has the charcoal cannister, which has a different purpose. Dad's GTO has a factory return line but doesn't have either cannister, no vapor cannister and no charcoal cannister. GM was funny about that stuff, I guess depending on what the EPA was requiring at the time and/or what plant the car was built or what state it was destined to be sold in.

right, but only the early year cars had that EEC standpipe on the rear seat, my 72 had that but i eliminated it.
charcoal canisters on most or all 73/74 or so & up years were up front in the engine bay & used a separate line than the vapor return line off the pump.
