Q: What is the purpose of the EVAP charcoal canister for the Honda CRX?
A: The vapor canister is part of the Evaporative Emission Control System, which prevents the escape of raw gasoline vapors from the fuel tank and carburetor. The vapor canister is designed to absorb fuel vapors under certain conditions. The canister is a coffee can-sized object located in the engine compartment. Label the hoses leading to the canister before disconnecting them, then, remove the old canister from its mounting bracket and discard it. Install the new canister and connect the hoses as before. The canister does not require periodic replacement. The entire system requires a careful operational check with a vacuum gauge at 60,000 miles (96,500 km).
