Attwood Carbon Canister Kit

The Attwood Carbon Canister Kit (MPN 99CC150-1S) is a compact emissions control system designed to reduce hydrocarbon vapors from entering the atmosphere on marine and powersports vehicles. As a mechanic familiar with fuel system maintenance, you'll recognize this as essential equipment for any vehicle that needs to meet environmental standards while maintaining proper fuel tank pressurization. The carbon canister serves as the core component in a complete vapor recovery system, preventing fuel overflow spit-back and ensuring consistent tank fill levels during refueling.

This system operates by trapping fuel vapors in engineered activated charcoal before they escape through the vent line. The canister works in tandem with purge valves and vent lines to route vapors back into the combustion chamber during engine operation, where they're burned cleanly rather than released to the atmosphere. The lightweight design—tipping the scales at just 1 lb—makes integration straightforward on space-constrained applications without adding unnecessary weight or complexity to fuel system plumbing. The engineered charcoal media effectively absorbs hydrocarbon molecules while the sealed housing prevents vapor leakage during storage or idle periods.

Technicians working on marine engines, small-displacement powersports equipment, and compact automotive applications will find this Attwood kit particularly valuable for emission compliance repairs and system upgrades. Installation requires proper connection to fuel tank vent lines and purge system components; ensure all connections are sealed to maintain system integrity. This carbon canister kit is ideal for restoration projects, emissions system replacements, or new builds where environmental performance and fuel system reliability are equally important.
