The fuel tank change occurred in April/May 1974. The carbon canister moved off the top of the fuel tank prior to this change. Was it at the end of calendar year 1973 or at the model change in the summer of 1973?

@ starbear.

your car is a 2.0?

they must have had provision in the body shells for the changeover to engine bay cannister before the new calendar year commenced. admittedly fairly minor changes to the shell.

they seem to be doing two things in 74. first changing to a plastic evap cannister (i might be wrong) and then changing its position (3 times?).

wonder if the plastic cannister worked up front properly on L jet 1.8 cars.
its the first time airflow meter system is used on a car.
engine fan did pressurize (not much admittedly) the evap cannister that leads into the air cleaner up stream of the meter flap. must influence the system? maybe only minor?
they moved that cannister around 3 times in a very short period of time.
