Carbon canister on top of fuel tank Options

[356drb]

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?

another thought.
since this stuff is very fresh in my mind having just re-plumbed the car.

until jan this year it was a bone stock, unmolested preserved car. 1.8. L jetronic.

the plumbing shown in the factory manual absolutely accords with what was in the car.
the fan bleed feed supplies from the opposite side to the fuel tank vent line and air cleaner hose line.

this conflicts with what i looked up in the haynes manual. the haynes manual has a diagram that suggests it is the other way around.

i ignored the haynes manual and went with the car and the factory manual.
i knew the hoses were original on the car and trusted that.

i don't know if L jets are plumbed opposite to D jets. never really studied a D jet.

but it strikes me the original configuration of the cannister up front could mean there is a possibility of plumbing it up wrong, just depends i guess on how that hose from air cleaner and from fan join to hoses running length of car in/under engine bay. don't know as i have never studied any earlier cars to that level of detail? not really familiar with a D jet.

perhaps another good reason they put the cannister in the engine bay was in order for mechanics servicing car to know they were getting the plumbing right if they had disconnected it entirely for some reason. especially with L jets. i don't think you would want to mess that up with an L jet.
