Attwood Marine 99CC Carbon Canister, 5/8 in Vent Hose, EPA/CARB, Ethanol-Compatible

Overview

This Attwood Marine carbon canister is a fuel vent vapor-control component for marine fuel systems that need an EPA-rated canister matched to tank capacity and installation location. The range uses 5/8 inch vent hose and includes compact, standard, engine-compartment, and large-vessel configurations for different vessel layouts.

Each canister uses engineered charcoal media to reduce fuel vapor emissions from the vent line, while the low-permeation shell helps reduce overall system emissions. The provided bracket setup allows mounting in any orientation, which is useful when space around fuel tanks, lockers, bilge areas, and engine spaces is limited.

The variants cover EPA trailerable vessel capacities from 70 gallons to 420 gallons and EPA non-trailerable vessel capacities from 110 gallons to 660 gallons. The heat-shield version is the one intended for engine-compartment installations where a pre-installed composite heat shield is required.

Key features

• Fuel vent carbon canister range for marine evaporative-emissions control systems.
• Fits 5/8 inch vent hose for common marine fuel vent plumbing.
• Engineered charcoal media helps reduce hydrocarbons released through the tank vent line.
• Low-permeation shell helps reduce overall fuel-system emissions.
• Can be mounted in any orientation using the provided brackets, which helps when routing around tanks, stringers, bulkheads, and service access points.
• Compatible with ethanol-blended fuels.
• EPA-rated capacities cover compact installations through large-vessel fuel systems.
• Heat-shield option includes a pre-installed composite shield for engine-compartment use.

Variants

This product is offered in several canister configurations so the canister capacity and heat-shield requirement can be matched to the boat’s fuel system layout.

The main differences are canister class, EPA-rated tank capacity, and whether the unit includes the engine-compartment heat shield. The 5/8 inch vent hose fitment, ethanol-blended fuel compatibility, low-permeation shell, and bracket mounting approach are consistent across the listed configurations.

• 99CC085-1S: Standard canister with no engine-compartment heat shield. It is rated for 220 gallons trailerable and 350 gallons non-trailerable under EPA applications, making it a fit for larger fuel systems than the compact version.
• 99CC045-1S: Compact canister with no engine-compartment heat shield. It is rated for 70 gallons trailerable and 110 gallons non-trailerable under EPA applications, which suits smaller fuel tanks where space is tighter.
• 99CC085HSA1S: Standard canister with an engine-compartment heat shield. It carries the same 220 gallon trailerable and 350 gallon non-trailerable EPA capacities as the standard version, with a pre-installed composite heat shield for engine-space placement.
• 99CC150-1S: Large vessel canister with no engine-compartment heat shield. It is rated for 420 gallons trailerable and 660 gallons non-trailerable under EPA applications for high-capacity fuel systems.

Installation and fit

Confirm the vessel’s fuel tank capacity, trailerable or non-trailerable classification, vent hose size, and mounting area before selecting a configuration. The canister should be installed as part of the fuel vent system where it can be secured, protected from direct liquid fuel or water exposure, and kept accessible for inspection.

The provided bracket mounting arrangement gives the installer flexibility with orientation, which matters on boats where fuel-system components often share space with tanks, harnesses, steering gear, pumps, and structural members. The engine-compartment variant should be used when the installation requires the integrated heat shield.

Use on board

This canister range is a practical match for builders, service yards, and boat owners replacing or configuring an EPA-compliant marine fuel vent system. It is most relevant on gasoline-powered boats where vapor control, vent-hose routing, and tank-capacity matching are part of the fuel-system service or refit.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
