You say you have a 71 Duster. FSM says all 71's have it. The 70 FSM says only certain ones have it. So if it's a 70 without ECS then you don;t have it
It's a 71 but it doesn't matter if I have the ECS or not at this point. I guess it had the right filler tube, but the wrong tank, and is missing the ECS tube. Then I turned around and bought a replacement tank of the same wrong type. That explains why I don't have a vent setup on the car.
Now that I've found how the 70s are run, I know what I need to hunt down to make it work.
