Fuel Evaporation System: Description
System prevents gasoline vapors from escaping into atmosphere from fuel tank and carburetor. All models use a pressure/vacuum relief fuel filler cap, purge control diaphragm valve, thermovalve, two-way valve, charcoal canister, and connecting lines and hoses.
In addition, Accord models use a liquid/vapor separator pipe, air vent cut-off diaphragm, vacuum holding solenoid valve, carburetor fuel cut-off solenoid valve, power valve control solenoid, and a control unit.
