Attwood Standard Carbon Canister for Fuel Systems

The Attwood standard carbon canister is a vapor-management component for compatible marine fuel systems. It is built to capture hydrocarbon vapors from the fuel-tank vent circuit rather than allowing those vapors to discharge directly through a conventional open vent during normal system operation.

Activated carbon inside the canister adsorbs fuel vapor while the surrounding vent system manages tank breathing. Correct canister sizing, orientation, hose routing, and connection to the compatible tank and vent hardware are important because the component operates as one part of an integrated marine evaporative-emissions system.

Confirm that this standard canister matches the vessel’s Attwood fuel-system design and applicable tank capacity or system specification before installation. Keep vent lines free of kinks and liquid traps, mount the canister as directed, and inspect the system for damaged hoses, loose fittings, fuel saturation, or other conditions that could impair ventilation.

• Activated carbon adsorbs hydrocarbons that would otherwise pass directly out of the tank vent.
• The canister works with compatible tank, vent, and fill components as part of the overall fuel system.
• Correct hose routing and canister installation allow the vent circuit to function while managing vapor.
• Checking hoses and fittings helps identify restrictions, saturation, or damage that can affect ventilation.
