Detailed Description

This vapor canister is made to match the original equipment evap canister used on certain vehicle years, makes, and models. The Dorman 911-812 uses a charcoal filter element inside a plastic housing to store fuel vapors from the evaporative emissions system, helping the vehicle route vapors properly instead of releasing them to the atmosphere. It is a practical replacement for select Hyundai Sonata, Hyundai XG350, Kia Amanti, Kia Optima, and Hyundai XG300 applications.

This part cross-references Standard Ignition CP3258 for the same application.

• Fuel vapor leaks caused by a damaged canister housing
• Check engine light concerns tied to EVAP system performance
• Fuel odor issues from a saturated or cracked vapor canister
• Failed emissions inspection results linked to EVAP system problems

Installation Notes and Tips

• Verify port count and port diameters before installation: 3 ports, with 0.438 in. and 0.625 in. outside diameters
• Mounting hardware is not included
• Confirm vehicle-specific fitment by year and model before ordering
• Inspect EVAP hoses and related components for damage during replacement
