M125 fuel evaporation

1- Fuel level sensor 2- Fuel tank 3- Fuel pump 4- Oil-air separator (welded inside the fuel tank) 5- Fuel tank cap 6-

Adsorption/vent pipe 7-High pressure fuel pipe 8-Carbon tank 9-Carbon tank solenoid valve 10- Solenoid valve intake pipe 11-

solenoid valve outlet pipe 12-throttle valve body assembly

Fuel evaporation:

Oil and gas → oil and gas separator (inside the oil tank) → adsorption/vent pipe → solenoid valve intake pipe → solenoid valv

outlet pipe → throttle valve body assembly → intake manifold → cylinder
