Capture fuel tank vapors and help keep your evaporative emission system working as the factory intended with the Standard Ignition vapor canister, part number CP455. It fits many vehicles, among them the 2004-2016 Chevrolet Silverado 1500, 2004-2016 GMC Sierra 1500 and 2004-2007 Chevrolet Silverado 2500 HD. See the "Vehicles it fits" section for the full list and engine details.
This fuel vapor canister collects vapor from the fuel tank and holds it until the engine's purge system draws it in to be burned, so the vapor is not vented to the atmosphere.
Signs a vapor canister may need replacing include a check engine light with EVAP-related codes, a fuel odor around the vehicle, or a fuel nozzle that keeps clicking off while refueling. These symptoms can have other causes, so diagnose the EVAP system first. If a failed canister is the cause, this part replaces it.
