Vapor Canister (Charcoal Canister)

Vapor canisters (Charcoal canisters) are essential components in a vehicle’s evaporative emission control system (EVAP). Their primary job is to capture and store fuel vapors from the fuel tank, preventing these harmful hydrocarbons from escaping into the atmosphere. The charcoal, usually activated carbon, absorbs these vapors When the engine runs, they’re purged and burned off in the combustion process. All fuel injection systems **REQUIRE** a vapor/charcoal canister for proper tank venting. All fuel tanks should be vented through a vapor/charcoal canister.
