What is the reason why BMW Brilliance 320 has a strong gasoline smell?

1. The gasket in the water tank cover is aged or uneven (replace).

2. The nozzle and throttle valve have not been cleaned for a long time, resulting in insufficient gasoline combustion (cleaning).

3. The gasoline filter is dirty or the connecting hose interface is loose and aging (replacement).

4, gasoline purification carbon canister dirty or failure (replacement)

5. Oil tank connecting hose is aging and loose (replacement)

6, the car sealing performance is not good (repair)

If all the above reasons are solved, your car should no longer smell of gasoline.
