Does anyone have had fuel tank or fuel filler pipe smell that is worse than gas smell. Is it possible to wash the fuel tank aqnd rails with something taking it off? I have used 2 years ago additives that made my car smell even outside of car terribly and now you cannot smell the smell actually but it is affecting my health already. Some week ago I had water canister from plastic in the car trunk near the fuel filler pipe rigt side and it smelled like terrible. Some weeks ago i changed fuel filter on my V35 and the filter also smelled terribly, not with gas smell but much worse . Any suggestions?
