Integrated Fuel Systems Overview EPA Certified / CARB Approved Carbon Canister Fuel Systems
The VaporTec fuel pressure management system ensures that a boat’s fuel system constantly maintains proper vapor pressure in all situations. This eliminates any unintended excess pressure which can seriously damage a boat or engine. Carbon canister systems utilize an engineered charcoal canister to reduce hydrocarbons entering the atmosphere. Other
components of a carbon canister system are designed to ensure the tank fills to the proper level every time without spit-back or well-back. All Attwood carbon canister systems are designed to ensure liquid fuel or water does not reach the canister and are compatible with Jerry Can and marine nozzle refueling.
