Help keep fuel-tank vapor contained with the Standard Ignition Vapor Canister CP3158, a direct-fit OE replacement that stores fuel vapor until the evaporative emission (EVAP) system purges it into the engine to be burned. It fits many Dodge and Ram trucks, among them the 2004-2008 Dodge Ram 1500, 2012-2023 Ram 2500 and 2006-2010 Dodge Ram 2500.
Signs a vapor canister may need replacing include a check engine light with EVAP-related codes, a raw fuel odor, trouble filling the tank, or a cracked housing. These symptoms can have other causes, so diagnose the EVAP system first. If a failed canister is the cause, CP3158 replaces it.
