I noticed a week ago or so that when i get into my car ( a 1999 Peugeot 106 ) there's a very noticeable smell of gas, what's weird is that once you get going the smell dissapears , in the engine compartement everything is fine and i can't see any leaks and it never smells under there, the air coming out of the hester smells fine too, i can't see any leaks under the car either, i do have a small canister with about 4 Liters of gas in there but it already smelled before i had it since i ran out of gas a few days ago when i was getting to work...
