Storage and breathing share a path
The training source describes activated charcoal holding fuel vapors until the engine purges them. The canister also sits in the system’s breathing path. That makes vapor storage and path restriction different diagnostic questions; a symptom alone does not identify the canister as the failed part.

Locate the restriction before naming the part
The Dart’s outlet path includes a canister, ESIM and remote filter. In the video, improved flow when the remote outlet was separated pointed downstream; dirt was found in the remote filter. The presenter replaced the filter and reported a successful fill-up.
| Reported finding | Interpretation | Outcome boundary |
|---|---|---|
| Repeated nozzle shutoff. | An outlet restriction was investigated. | The symptom alone did not condemn the canister. |
| Flow improved with the remote outlet separated. | The restriction was narrowed to that outlet path. | This does not establish a transferable disassembly procedure. |
| Filter replaced; fill-up reported successful. | The original complaint was revisited. | No long-term follow-up is shown. |
