Checking the fuel vapor extraction system (Mazda Capella GC)

1. The system performs the functions of drawing fuel vapors from the fuel tank and carburetor, condensing them in a carbon canister and then returning the fuel to the fuel system.

2. The first sign of a malfunctioning fuel vapor removal system is a strong smell of gasoline in the engine compartment. If you detect the smell of gasoline, inspect the charcoal canister located on the heat-insulating shield of the engine compartment (photo) and the system hoses.



3. To test the system's operation, place your hand under the canister, warm up the engine to normal operating temperature, and slowly increase the engine speed. If air is sucked into the base of the canister, the system is working properly.

4. The fuel vapor extraction system is described in more detail in Section 6.
