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?

Here is a 10/73 car with the front mounted canister.
I don't think a calendar year change would have been issued. Model year yes. Perhaps a mid-model year change if it was linked to a change in legal requirements, where teh emissions reqs did not change at the calendar year. Both cars with front and engine bay mounted canisters would function the same. The change required a different mounting bracket for the engine bay (congesting the engine bay), eliminated the 2 big supply/return air plastic tubes on the driver side valence and replaced them with shorter rubber hoses in the engine bay. No real benefit or reason as far as I can understand. So far. Attached image(s) |
