fuel odor, difficult to start after fill up

CEL on, error code P0446, replaced fuel vent valve, fuel sending gasket, inspected sending unit for cracks.
At fill up, only filled 3/4.

Purge line blocked. Flow resistance of EVAP canister too high.

Disconnect purge line from EVAP canister. Blow through purge air line with compressed air. If blocked or leaking replace. If line ok I think the canister is then replaced.
