Dorman - OE Solutions Vapor Canister P/N:911-257
Capture and store fuel-tank vapors with the Dorman vapor canister 911-301 from Dorman - OE Solutions, an evaporative emissions charcoal canister made to match the original equipment unit. It fits many vehicles, among them the 2004-2012 Chevrolet Colorado, 2004-2012 GMC Canyon and 2006-2010 Hummer H3. See the Buyer's Guide tab for the full list and engine details.
In the evaporative emissions (EVAP) system, the canister holds fuel vapors from the tank so they can later be drawn into the engine and burned instead of escaping to the atmosphere. If a cracked or failed canister is behind an EVAP fault, this Dorman evap canister replaces it.
